Presentation
Abdominal discomfort.
Patient Data
Oval, arterially hyperenhancing mass that is partially exophytic and arising from the dudenojejunal junction. No other concerning findings in the abdomen or pelvis.
Case Discussion
This mass has features that are more typical for GIST than other small bowel tumors such as adenocarcinoma or lymphoma. Carcinoid tumor would be another consideration but the partially exophytic nature is more typical for a GIST. Either way the next right step is to have an endoscopic US and biopsy, which revealed the diagnosis of a GIST, which was later surgically resected.
Notice that biphasic (late aterial + PVP) is superior for the detection of metastases related to carcinoid/neuroendocrine tumor or RCC, but is not necessary in this case.
