18F-FDG PET/CT imaging identified an extremely rare case of mesenteric vein tumor thrombosis associated with diffuse metastatic small cell carcinoma in an 87-year-old woman.
This case highlights the rare presentation of superior mesenteric vein tumor thrombosis associated with small cell carcinoma on 18F-FDG PET/CT.

The presence of intravascular tumor thrombus alters the staging, prognosis, and treatment paradigms of cancer patients. It most commonly complicates renal cell carcinoma, adrenocortical carcinoma, and hepatocellular carcinoma. Small cell carcinoma is a highly aggressive malignant neoplasm; however, venous tumor thrombus associated with small cell carcinoma is extremely rare. Herein, we report the fluorine-18-fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) findings in an 87-year-old woman presenting with diffuse metastatic small cell carcinoma and superior mesenteric vein tumor thrombosis.
