This paper reports a fatal case of a 57-year-old man with multiple supratentorial and infratentorial cavernomas and a previously documented posterior fossa developmental venous anomaly (DVA). Using sequential CT and MRI/angiography, the authors found spontaneous thrombosis with loss of DVA filling, followed by rapid neurological deterioration, cerebellar parenchymal hemorrhage, and posterior fossa hypertension consistent with venous infarction/venous ischemic complications. The main caveat is that this is a single retrospective case with no systematic comparison group and no evidence of changes in the cavernomas during the episode, limiting causal conclusions about how the cavernomas and the DVA contributed. This paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.

Abstract

Abstract A 57-year-old male with multiple supratentorial and infratentorial cavernomas presented with subacute-onset headache, tinnitus, and worsening neurological deficits. Imaging revealed spontaneous thrombosis of a previously documented developmental venous anomaly (DVA) in the posterior fossa, resulting in cerebellar parenchymal hemorrhage and posterior fossa hypertension consistent with venous infarction. This case highlights the rare occurrence of spontaneous DVA thrombosis, emphasizing its potential for severe complications, such as venous ischemic infarction, parenchymal hemorrhage, venous congestion, or subarachnoid hemorrhage, as well as the importance of sequential imaging in documenting pathological progression.

This case highlights the rare occurrence of spontaneous DVA thrombosis, emphasizing its potential for severe complications, such as venous ischemic infarction, parenchymal hemorrhage, venous congestion, or subarachnoid hemorrhage, as well as the importance of sequential imaging in documenting pathological progression. cavernomas venous developmental anomaly thrombosis Figures Figure 1 Figure 2 Main Text A 57-year-old male has been under follow-up at our Neurosurgery Outpatient Clinic since 2002 because of multiple supratentorial and infratentorial cavernomas associated with previous hemorrhages. His previous deficits included incomplete left hemiparesis, left hemihypoesthesia, internuclear ophthalmoplegia, cerebellar syndrome with ataxia, and dysmetry. In addition to cavernomas, previous imaging studies revealed a large developmental venous anomaly (DVA) in the posterior fossa, crossing the midbrain toward the right cerebellopontine angle cistern. The patient sought emergency care complaining of subacute-onset headache, tinnitus, and worsening preexisting neurological deficits. Subsequently, imaging studies were conducted. Computed tomography (CT) revealed spontaneous hyperdensity of the DVA that failed to fill with contrast on venous CT angiography. Subsequent magnetic resonance imaging (MRI) and angiography confirmed the absence of DVA filling, in contrast to prior imaging, indicating DVA thrombosis. The following day, the patient experienced rapid neurological deterioration, which progressed to a decreased level of consciousness. Follow-up CT showed cerebellar parenchymal hemorrhage associated with signs of posterior fossa hypertension, consistent with venous infarction. Ultimately, the patients experienced a fatal outcome. This clinical case illustrates a DVA associated with cavernomas that evolved with spontaneous thrombosis of the DVA drainage vein and consequent parenchymal hemorrhage in the posterior fossa. DVAs are anatomical variants of normal transmedullary veins responsible for draining cerebral white and gray matter. 1-3 Although usually asymptomatic, they can lead to severe clinical manifestations under specific circumstances, such as drainage vein thrombosis. 1,2 Histologically, DVAs consist of thickened hyalinized veins with few or no smooth muscle cells or elastic connective tissue. These structural abnormalities and low blood flow in the drainage veins increase the susceptibility to thrombosis. 1,2 Clinically, patients with DVA thrombosis may present with venous ischemic infarction, parenchymal hemorrhage, venous congestion, or subarachnoid hemorrhage. 2 To the best of our knowledge, this case is significant because of the rarity of spontaneous DVA thrombosis reported in the medical literature. Sequential imaging studies documented these pathological processes. Comparison with prior imaging was crucial to confirm DVA occlusion and correlate it with clinical outcomes. Despite the presence of multiple cavernomas, no related changes or hemorrhages were observed during this clinical episode. 3 Declarations Acknowledgment: none. Funding: none.
