Jejunal bleeding vessel at endoscopy 42 x 37 x 31 mm mildly lobulated solid vividly enhancing/hypervascular mass in the right upper quadrant abuts the loop of jejunum marked by endoscopic clips, but may be centred over mesentery. Evidence of AV shunting into a prominent vein that drains into the portal venous system. The arterial supply appears to be from a jejunal branch. No evidence of active contrast extravasation/bleeding. No surrounding stranding. No 2nd lesion. No liver lesion. Minor basal atelectasis. Conclusion Mass lesion relating to the endoscopically marked jejunum is most probably a GIST tumor, although necrosis would be commonly seen for this size. Other hypervascular differentials include carcinoid or glomus tumours. The AV shunting may be related to the tumor, or be related to the clipping.
