Key result
FDG PET/CT successfully depicted a rare case of right iliac vein tumor thrombosis following low anterior resection in a patient with rectal cancer.
Why the study?
Venous tumor thrombus is a rare complication of rectal cancer that seldom involves the common iliac vein, with only a few cases reported.
Case Report (n=1)
FDG PET/CT can be useful in identifying rare venous tumor thrombus in the common iliac vein in patients with rectal cancer.

May aid rare venous thrombus detection in rectal cancer; hypothesis-generating and should not change practice.
Venous tumor thrombus is a rare complication of rectal cancer but is more common in other types of cancer, like renal cell carcinoma and hepatocellular carcinoma. The usual site of tumor thrombus in rectal cancer patients is the inferior mesenteric vein (IMV), which is seldom seen in the common iliac vein, with only a few cases reported till now. We present a case of fluorodeoxyglucose (FDG) avid right iliac vein tumor thrombosis after low anterior resection in a patient with rectal cancer and review the literature.
