Development of enterohepatic fistula after embolization in ileal gastrointestinal stromal tumor: A case report

Figure 1 Initial abdominopelvic computed tomography findings. Enhanced computed tomography shows a 5.7 cm × 5.2 cm heterogeneous enhancing liver mass connected with a small mass of the distal ileum (arrows). A: Axial view; B: Coronal view.

Figure 2 Large protruding mass on the distal ileum (enteroscopic findings). A large protruding mass with ulceration was found on the distal ileum.

Figure 3 Angiographic findings (post-embolization state). Angiography shows that the hepatic mass (arrows) was not supplied by the right hepatic artery after embolization.

Figure 4 Microscopic findings (Endoscopic biopsy specimen in the ileum). A: Microscopic image of the specimen demonstrating spindle cells (HE, × 200); B: The tumor cells were strongly positive for c-KIT (c-KIT, × 400).

Figure 5 Abdominopelvic computed tomography findings after embolization. Internal necrosis and direct communication (arrows) with the small bowel were identified in the liver mass. A: Axial view; B: Coronal view.

Figure 6 Gross findings of resected segment of the distal ileum. It showed a large fistula orifice (arrow) which connected with the adjacent liver, as proven by food material in the liver mass.
