Abstract

Tumour thrombi are a rare but serious complication of malignancy. It involves extension of organised collection of neoplastic
cells into adjacent blood vessels, in contrast to a bland thrombus which consists of platelets and fibrin. It occurs more
commonly in renal cell or hepatic cell carcinoma. Tumour thrombi are often asymptomatic and incidentally detected on
imaging, however, their presence can affect staging, treatment options and prognosis of the patient. We present a rare case
of a FDG avid tumour thrombus in left brachiocephalic vein in a patient with previously treated metastatic urothelial
carcinoma and a second primary lung carcinoma.
Keywords: Tumour thrombus, Urothelial carcinoma, FDG PET-CT, pulmonary adenocarcinoma
