Abdominal wall endometriosis is rare. Malignant transformation of abdominal wall endometriosis is extremely rare. We describe FDG PET/CT findings in a case of clear cell carcinoma arising from abdominal wall endometriosis with multiple lymp…

Fibroblast activation protein inhibitor (FAPI) PET is an emerging molecular imaging modality that is widely used in oncology and increasingly investigated in nononcologic diseases. Abdominal wall endometriosis (AWE) is a rare form of endome…

Endometriosis is a chronic condition in reproductive-age women, and diagnosis can be delayed for 4-11 years due to nonspecific symptoms and limited imaging. This underscores the need for new methods to overcome these diagnostic challenges. …

A 44-year-old woman with biopsy-proven endometriosis underwent 68 Ga-FAPI-04 PET/CT. MRI revealed bilateral ovarian endometriomas, uterine adenomyosis, and deep pelvic endometriotic lesions. FAPI PET/CT demonstrated concordant uptake in dee…

Xanthogranulomatous cholecystitis (XGC) is an uncommon inflammatory disease of the gallbladder. We report a case of XGC with elevated activity of 18 F-FDG and 68 Ga-FAPI (fibroblast activating protein inhibitor), which mimics malignancy. Ou…

Endometriosis is a benign condition characterized by chronic inflammation and fibrosis. We report the findings of endometriosis at the rectouterine pouch on 68 Ga-FAPI-04 PET/CT scan in a 25-year-old woman. The finding was initially thought…

Endometriosis is a chronic inflammatory estrogen-dependent benign disease. It is defined as the endometrium growing outside the uterine cavity and the myometrium. It usually has low FDG uptake but rarely occurs in the ureters. We reported a…

Lung endometriosis is a rare condition. A 44-year-old woman with known lung endometriosis and radiological follow-up showed progression of bilateral lung affection at control CT, with an enlarged solid nodule with respect to previous contro…

We describe a case of adenomyosis that reduced in size in a patient with lymphoma on receiving chemotherapy. A 48-year-old woman with worsening left flank pain was diagnosed with follicular lymphoma. [ 18 F]FDG PET/CT revealed multiple hype…

A 35-year-old woman with a history of laparoscopic myomectomy presented with repeated abdominal pain. Contrast-enhanced abdominal and pelvic CT showed multiple enhancing solid or mixed cystic and solid peritoneal masses, and an enhancing ut…

99m Tc-RBC bleeding scan in a 17-year-old adolescent girl showed an increased focal activity in the pelvis. However, SPECT/CT showed that this activity was located in the uterus, which was considered a normal variant considering that the pa…

Extrauterine endometrial stromal sarcoma (EESS) is extremely rare, especially with the colorectum involvement. We describe 18 F-FDG PET/CT findings of EESS in the sigmoid colon and rectum in a 46-year-old woman who complained diarrhea. 18 F…

INTRODUCTION: Endometriosis is a common gynecologic condition that may be visualized on 18F-FDG PET/CT and mimic lesions of malignancy. We analyzed the interference of known or suspected endometriosis in reporting 18F-FDG PET/CT performed i…

Umbilical endometriosis is a rare event. A 44-year-old woman complained of a palpable abdominal mass with bloody secretion and chronic abdominal pain for 2 months. 18 F-FDG PET/CT images demonstrated multiple foci of increased tracer uptake…

A 27-year-old woman with swelling left leg, groin pain, and increased serum CA125 level underwent FDG PET/CT to evaluate a pelvic mass revealed by an MRI performed from an outside hospital. A large hypermetabolic solid mass in the left pelv…

A 33-year-old woman with Hodgkin disease Ann Arbor stage IIA underwent baseline F-FDG PET/CT scanning. The scan showed gross multicystic enlargement of both ovaries and a nodule at the edge of the right ovary with intense FDG uptake (SUVmax…

Endometriosis is a frequent and benign cause of disabling abdominal pain, for which a diagnosis suspicion is clinically raised, but its confirmation necessitates a surgical exploration by laparoscopy. Foci of endometriosis proliferate under…

Endometriosis is a common gynecologic condition of the premenopausal years. However, postmenopausal endometriosis is rare (2.2%) and thought to be related to high level of circulating estrogen, especially in hormonal replacement therapy. We…

Abdominal wall endometriosis (AWE) is defined as endometrial tissue located superficial to the peritoneum, which usually develops in a surgical scar of cesarean delivery. Malignant transformation of AWE is a very rare disease. The most freq…

Endometriosis is a benign disease characterized by the implantation of functional endometrial tissue in ectopic locations. We present a case of a 42-year-old woman with widespread endometriosis that mimicked ovarian malignancy on FDG PET/CT…

A 44-year-old woman had a history of papillary thyroid carcinoma and underwent total thyroidectomy and I ablation therapy. During the follow-up, 2-mCi I cancer workup showed an unusual shape of uptake in the pelvic region. Hybrid SPECT/CT r…

Abscess formation inside adenomyosis rarely occurred. A 49-year-old woman had adenomyosis for several years with the symptoms of menorrhagia and dysmenorrhea. She presented with fever of unknown etiology for 3 weeks. 67Ga SPECT/CT demonstra…

We present the case of a 23-year-old woman with 2 episodes of hemoptysis. Computed tomography showed a small mass lesion with an adjacent cyst in the left lower lobe. On whole-body fluorodeoxyglucose positron emission tomography/computed to…

A 40-year premenopausal woman was referred by her treating oncologist for F-18 fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) to rule out disease recurrence or metastasis. She had completed therapy for Hodg…

A 37-year-old woman with non-Hodgkin lymphoma had a F-18 fluorodeoxyglucose positron emission tomography (FDG PET) scan which showed 2 foci of pelvic uptake initially thought to represent iliac nodes. However, a computed tomography scan dem…
