There is a large, lobulated, heterogeneously enhancing mass arising from the submucosa of the fundus of stomach, with areas of necrosis and cystic degeneration within.The mass has both intraluninal and exophytic components. There are central areas of ulceration/ cavitation within this lesion which communicate with the gastric lumen. Multiple air foci are also noted in the cavitatory portion. The exophytic component shows necrotic areas within and is abutting the pancreas and spleen and encasing the splenic artery. Splenic vein in the region of mass is not well visualized with multiple perigastric and mesenteric collaterals.Rest of the overlying mucosa is normal. The imaging features are suggestive of malignant GIST.
The liver shows multiple large round iso to hypodense lesions with variable enhancement on arterial phase, suggestive of metastatic liver lesions.
There is mild ascites, however the peritoneum is unremarkable.
