Somatostatin-receptor avidity of pancreatic neuroendocrine tumor thrombus in porto-caval venous systems on (99m)Tc-Octreotide and posttherapeutic (177)Lu-DOTA-TATE scans

A 62-year-old woman with a history of abdominal pain presented with multiple hepatic lesions and dilatation of portal, splenic and superior mesenteric veins on the magnetic resonance imaging referred for a (99m)Tc-octreotide scan. Accordingly, similar octreotide-avid lesions were found as well as an...

Sumario:A 62-year-old woman with a history of abdominal pain presented with multiple hepatic lesions and dilatation of portal, splenic and superior mesenteric veins on the magnetic resonance imaging referred for a (99m)Tc-octreotide scan. Accordingly, similar octreotide-avid lesions were found as well as an uptake in the epigastric region conforming to the anatomy of the portocaval venous system, compatible with a tumor thrombosis. Then, the patient underwent two cycles of therapy with (177)Lu-DOTA-TATE, on that the same appearance was observed. The uptake in the tumor thrombus remained somewhat unchanged, but clinically, a significant improvement of the intractable ascites was achieved.
