Stretching and compression of the ICA owing to sudden acceleration, deceleration, and rotational forces are risk factors for ICA dissection. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is believed to trigger an inflammatory response exacerbating endothelial dysfunction leading to arterial dissection. Although levodopa-induced cervical dyskinesia in Parkinson’s disease often manifests as choreiform movement, dissection has not been reported in such patients. Case Presentation: A 51-year-old man with Parkinson’s disease (PD) presented with gradually worsening neck pain and transient aphasia one week after mild coronavirus disease 2019 (COVID-19) infection. The patient presented with levodopa-induced cervical dyskinesia. Magnetic resonance imaging revealed acute ischemic stroke in the left parietal lobe and an intramural hematoma with an area of stenosis in the left ICA. The patient was diagnosed with a left ICA artery dissection. Conclusions The quick cervical movement under COVID-19-related vessel wall vulnerability may cause ICA dissection. Although patients with PD often have neck pain, ICA dissection should be included as a differential diagnosis if the patient has COVID-19. Internal carotid artery dissection COVID-19 Parkinson’s disease dyskinesia stroke Figures Figure 1 Figure 2 Figure 3 Background Internal carotid artery (ICA) dissection has been reported to be a rare disease; however, the annual incidence rate has increased from 2.30 per 100,000 person-years to 8.93 per person-years over the past 19 years because of the evolution of vascular imaging techniques [ 1 ]. However, the actual incidence may be higher in asymptomatic patients. Prior trauma is identified in only up to 40% of cases, and most traumatic events (up to 90%) are mild or trivial insults [ 2 ]. Stretching and compression of the ICA owing to sudden acceleration, deceleration, or rotational forces can increase the risk of dissection [ 3 ] . Recently, it has been proposed that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) triggers an inflammatory response that exacerbates endothelial dysfunction leading to dissection [ 4 ] [ 5 ] [ 6 ] [ 7 ]. Although the cause of coronavirus disease 2019 (COVID-19) and arterial dissection is uncertain, 42 patients with arterial dissection have been reported in a recent review [ 4 ]. Here, we describe a patient with Parkinson’s disease (PD) who developed levodopa-induced neck dyskinesia and cerebral infarction due to ICA dissection during COVID-19. Case presentation A 51-year-old man with levodopa-induced neck dyskinesia presented to the neurology clinic with gradually worsening neck pain 1 week after a mild COVID-19 infection. He had experienced transient motor aphasia for approximately 2–3 hours the previous day. He was clinically diagnosed with Parkinson’s disease (PD) 6 years ago based on pre-established criteria [ 8 ]. The initial signs of PD, such as bradykinesia, rigidity, and resting tremor, were observed at 44 years of age. Neuromelanin imaging, 123 I-metaiodobenzylguanidine myocardial scintigraphy, and dopamine transporter imaging supported the diagnosis (Fig. 1 , A-E) [ 9 ]. Levodopa improved his symptoms, but a dose increase and additional medication were needed because of the progression of PD. He exhibited neck dyskinesia during the on-state and complained of neck pain due to cervical spondylosis since the past year (Fig. 1 F). The site of neck pain changed slightly to left side 1 week before the presentation. He did not have any vascular risk factors such as smoking, hypertension, hyperlipidemia, or diabetes. No family history of arterial dissection, collagen vascular disease, inherited arteriopathies, fibromuscular dysplasia, extreme vessel tortuosity, moyamoya disease, or cystic medial necrosis was noted. The PD medication included levodopa/carbidopa (150/15 mg, 5 times a day), entacapone (100 mg, twice a day), selegiline (2.5 mg twice a day), and ropinirole tape (16 mg). His neurological findings were normal except for parkinsonism. The Mini-Mental State Examination score was 26 (lost 4 points in series 7). Laboratory tests including protein C, protein S, antithrombin III, ferritin, D-dimer, and autoimmune antibody screening were normal. C-reactive protein was slightly elevated (0.46 mg/dL, normal < 0.14 mg/dL). Brain computed tomography (CT) revealed a low-density area in the left parietal lobe (Fig. 2 A). Elongated styloid processes were not observed. Additional brain magnetic resonance imaging (MRI) detected acute infarctions in the left hemisphere (Fig. 2 , B and C), and an intramural hematoma was observed in an area of stenosis in the left ICA (Fig. 2 , D-G). The patient was admitted with left ICA dissection [ 10 ]. Dissection occurred approximately 2 cm proximal to the base of the skull (Fig. 2 , H and I). Antiplatelet therapy with 100 mg/day aspirin was initiated. Amantadine (100 mg/day) was initiated to treat the levodopa-induced dyskinesia. The patient’s dyskinesia and neck pain improved gradually. The patient was discharged 10 days later without any sequelae and returned to work. On follow-up MRI performed 6 months later, the intramural hematoma had diminished (Fig. 3 ). Antiplatelet therapy was terminated based on literature [ 2 ]. DISCUSSION To date, neck dyskinesia-induced ICA dissection has not been reported in patients with PD. A previous report described that sudden violent neck tics can cause cervical artery dissection [ 11 ]. The mechanical stress of violent jerking motions of the head and neck has been reported as a potential causative factor of ICA dissection [ 3 ]. In the present case, however, we speculated that COVID-19 was a risk factor for the onset of ICA dissection, in addition to the mechanical stress of cervical choreiform movement due to dyskinesia. According to a recent review, 42 cases of arterial dissection associated with COVID-19 were reported as of October 2021. Aortic dissection was the most common (52.3%), followed by coronary artery dissection (23.8%) and, less commonly, cerebral, vertebral and ICA dissections (7.1% each) [ 4 ]. About 50% of the patients were aged between 45 and 59 years and the period between the onset of COVID-19-like symptoms and presentation to the hospital with symptoms/signs of arterial dissection ranged from 1 day to 8 weeks [ 4 ]. The age and onset date in the present case were consistent with previous data. Common risk factors included hypertension (60%), diabetes mellitus (15%), dyslipidemia (15%), and smoking (15%). No risk factors were identified in 47.6% of the patients as with the present case. Arterial dissection in patients with COVID-19 may occur secondary to an exaggerated inflammatory response that causes endothelial dysfunction. SARS-CoV-2 infects the host using the angiotensin-converting enzyme 2 receptor, which is expressed not only in the lungs and heart but also in endothelial cells [ 6 ]. Thus, endothelium throughout the body is at risk of SARS-CoV-2 [ 12 ]. The presence of SARS-CoV-2 viral particles in the capillary endothelia of a frontal lobe specimen was confirmed in an autopsy case [ 13 ]. Cervical artery dissection is rare; however, early detection and therapeutic intervention are crucial because dissecting aneurysm rupture or stroke can be life-threatening [ 5 ]. Although the relationship between ICA dissection and COVID-19 is uncertain, a previous case report of ICA dissection after mild COVID-19 supports this causative association [ 7 ]. In that report, acute neck pain occurred when the patient’s head was hyperextended during an oropharyngeal swab test for COVID-19 during follow-up, and MRI revealed ICA dissection. Although the timing of stroke symptoms and neck pain in this case was highly suggestive of a causal link between neck extension and the onset of dissection, the site of dissection was atypical for traumatic ICA dissection. The dissection might have occurred because of mechanical stress at the site of endothelial damage due to SARS-CoV-2 in our case and the previous case. We believe that the main mechanical stress in our case was levodopa-induced dyskinesia of the neck. Coughing and sneezing might be the factors that induced dissection. Amantadine (an NMDA receptor antagonist), which is reported to be the most effective treatment for levodopa-induced dyskinesia, improved neck dyskinesia [ 14 ]. Pain is highly prevalent in patients with PD, and the neck is one of the most common sites [ 15 ]. Cervical spinal deformity and forward head posture are associated with neck pain. A CT scan for our patient might not have been performed if he had not provided information on transient aphasia, since our patient complained of neck pain for a year, and the onset of neck pain was not acute. Supportive information for ICA dissection was that the site of his neck pain was slightly left-sided. Even in patients with PD and neck pain, cervical artery dissection may be included in the differential diagnosis if the patient has COVID-19. A major limitation of this study is that we conducted only physical/neurological examinations, blood tests, and imaging studies to rule out alternative mechanisms of ICA dissection, such as collagen vascular disease, inherited arteriopathies, fibromuscular dysplasia, extreme vessel tortuosity, or cystic medial necrosis. However, considering previous reports regarding SARS-CoV-2 and arterial dissection, further studies are needed to clarify the effect of COVID-19 infection on the vulnerability of the endothelium and arterial dissection.

He exhibited neck dyskinesia during the on-state and complained of neck pain due to cervical spondylosis since the past year (Fig.\u0026nbsp;\u003cspan refid=\"Fig1\" class=\"InternalRef\"\u003e1\u003c/span\u003eF). The site of neck pain changed slightly to left side 1 week before the presentation. He did not have any vascular risk factors such as smoking, hypertension, hyperlipidemia, or diabetes. No family history of arterial dissection, collagen vascular disease, inherited arteriopathies, fibromuscular dysplasia, extreme vessel tortuosity, moyamoya disease, or cystic medial necrosis was noted. The PD medication included levodopa/carbidopa (150/15 mg, 5 times a day), entacapone (100 mg, twice a day), selegiline (2.5 mg twice a day), and ropinirole tape (16 mg).\u003c/p\u003e \u003cp\u003e \u003c/p\u003e \u003cp\u003eHis neurological findings were normal except for parkinsonism.

C-reactive protein was slightly elevated (0.46 mg/dL, normal\u0026thinsp;\u0026lt;\u0026thinsp;0.14 mg/dL).

The patient was admitted with left ICA dissection [\u003cspan citationid=\"CR10\" class=\"CitationRef\"\u003e10\u003c/span\u003e].

The patient was discharged 10 days later without any sequelae and returned to work. On follow-up MRI performed 6 months later, the intramural hematoma had diminished (Fig.\u0026nbsp;\u003cspan refid=\"Fig3\" class=\"InternalRef\"\u003e3\u003c/span\u003e).

A previous report described that sudden violent neck tics can cause cervical artery dissection [\u003cspan citationid=\"CR11\" class=\"CitationRef\"\u003e11\u003c/span\u003e]. The mechanical stress of violent jerking motions of the head and neck has been reported as a potential causative factor of ICA dissection [\u003cspan citationid=\"CR3\" class=\"CitationRef\"\u003e3\u003c/span\u003e]. In the present case, however, we speculated that COVID-19 was a risk factor for the onset of ICA dissection, in addition to the mechanical stress of cervical choreiform movement due to dyskinesia.\u003c/p\u003e \u003cp\u003eAccording to a recent review, 42 cases of arterial dissection associated with COVID-19 were reported as of October 2021. Aortic dissection was the most common (52.3%), followed by coronary artery dissection (23.8%) and, less commonly, cerebral, vertebral and ICA dissections (7.1% each) [\u003cspan citationid=\"CR4\" class=\"CitationRef\"\u003e4\u003c/span\u003e]. About 50% of the patients were aged between 45 and 59 years and the period between the onset of COVID-19-like symptoms and presentation to the hospital with symptoms/signs of arterial dissection ranged from 1 day to 8 weeks [\u003cspan citationid=\"CR4\" class=\"CitationRef\"\u003e4\u003c/span\u003e]. The age and onset date in the present case were consistent with previous data. Common risk factors included hypertension (60%), diabetes mellitus (15%), dyslipidemia (15%), and smoking (15%). No risk factors were identified in 47.6% of the patients as with the present case. Arterial dissection in patients with COVID-19 may occur secondary to an exaggerated inflammatory response that causes endothelial dysfunction. SARS-CoV-2 infects the host using the angiotensin-converting enzyme 2 receptor, which is expressed not only in the lungs and heart but also in endothelial cells [\u003cspan citationid=\"CR6\" class=\"CitationRef\"\u003e6\u003c/span\u003e]. Thus, endothelium throughout the body is at risk of SARS-CoV-2 [\u003cspan citationid=\"CR12\" class=\"CitationRef\"\u003e12\u003c/span\u003e]. The presence of SARS-CoV-2 viral particles in the capillary endothelia of a frontal lobe specimen was confirmed in an autopsy case [\u003cspan citationid=\"CR13\" class=\"CitationRef\"\u003e13\u003c/span\u003e]. Cervical artery dissection is rare; however, early detection and therapeutic intervention are crucial because dissecting aneurysm rupture or stroke can be life-threatening [\u003cspan citationid=\"CR5\" class=\"CitationRef\"\u003e5\u003c/span\u003e]. Although the relationship between ICA dissection and COVID-19 is uncertain, a previous case report of ICA dissection after mild COVID-19 supports this causative association [\u003cspan citationid=\"CR7\" class=\"CitationRef\"\u003e7\u003c/span\u003e]. In that report, acute neck pain occurred when the patient\u0026rsquo;s head was hyperextended during an oropharyngeal swab test for COVID-19 during follow-up, and MRI revealed ICA dissection. Although the timing of stroke symptoms and neck pain in this case was highly suggestive of a causal link between neck extension and the onset of dissection, the site of dissection was atypical for traumatic ICA dissection. The dissection might have occurred because of mechanical stress at the site of endothelial damage due to SARS-CoV-2 in our case and the previous case. We believe that the main mechanical stress in our case was levodopa-induced dyskinesia of the neck. Coughing and sneezing might be the factors that induced dissection. Amantadine (an NMDA receptor antagonist), which is reported to be the most effective treatment for levodopa-induced dyskinesia, improved neck dyskinesia [\u003cspan citationid=\"CR14\" class=\"CitationRef\"\u003e14\u003c/span\u003e].\u003c/p\u003e \u003cp\u003ePain is highly prevalent in patients with PD, and the neck is one of the most common sites [\u003cspan citationid=\"CR15\" class=\"CitationRef\"\u003e15\u003c/span\u003e]. Cervical spinal deformity and forward head posture are associated with neck pain. A CT scan for our patient might not have been performed if he had not provided information on transient aphasia, since our patient complained of neck pain for a year, and the onset of neck pain was not acute. Supportive information for ICA dissection was that the site of his neck pain was slightly left-sided. Even in patients with PD and neck pain, cervical artery dissection may be included in the differential diagnosis if the patient has COVID-19. A major limitation of this study is that we conducted only physical/neurological examinations, blood tests, and imaging studies to rule out alternative mechanisms of ICA dissection, such as collagen vascular disease, inherited arteriopathies, fibromuscular dysplasia, extreme vessel tortuosity, or cystic medial necrosis. However, considering previous reports regarding SARS-CoV-2 and arterial dissection, further studies are needed to clarify the effect of COVID-19 infection on the vulnerability of the endothelium and arterial dissection.\u003c/p\u003e"},{"header":"Abbreviations","content":"\u003cdiv class=\"DefinitionList\"\u003e \u003cdiv class=\"DefinitionListEntry\"\u003e \u003cdiv class=\"Term\"\u003eICA\u003c/div\u003e \u003cdiv class=\"Description\"\u003e \u003cp\u003eInternal carotid artery\u003c/p\u003e \u003c/div\u003e \u003c/div\u003e \u003cdiv class=\"DefinitionListEntry\"\u003e \u003cdiv class=\"Term\"\u003eSARS-CoV-2\u003c/div\u003e \u003cdiv class=\"Description\"\u003e \u003cp\u003esevere acute respiratory syndrome coronavirus 2\u003c/p\u003e \u003c/div\u003e \u003c/div\u003e \u003cdiv class=\"DefinitionListEntry\"\u003e \u003cdiv class=\"Term\"\u003ePD\u003c/div\u003e \u003cdiv class=\"Description\"\u003e \u003cp\u003eParkinson\u0026rsquo;s disease\u003c/p\u003e \u003c/div\u003e \u003c/div\u003e \u003cdiv class=\"DefinitionListEntry\"\u003e \u003cdiv class=\"Term\"\u003eNMDA\u003c/div\u003e \u003cdiv class=\"Description\"\u003e \u003cp\u003eN-methyl-d-aspartate\u003c/p\u003e \u003c/div\u003e \u003c/div\u003e \u003c/div\u003e"},{"header":"Declarations","content":"\u003cp\u003e\u003cstrong\u003eEthics approval and consent to participate\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003eThe study was approved by the Ethics Committee of Mie University Hospital (H2018-032).
