Patient Data

Age: 56 years

There is a well-defined, large, lobulated, heterogeneously enhancing mass with internal gas locules and central necrosis, originates mostly from the right small bowel loops (ileum) at L1-L5 vertebrae level and causing mass effect on adjacent structures..

It is associated with minimal fat stranding and regional sub-centimetric mesenteric and right retro-crural lymph nodes.

No evidence of bowel obstruction.

Case Discussion

The patient underwent a computed tomography (CT) guided biopsy which revealed a gastrointestinal stromal tumor. So, surgical resection with mesenteric lymph node dissection was the plan.

Histopathology results confirmed the diagnosis.

Gastrointestinal stromal tumor (GIST) is a rare tumor originating in the digestive tract, often in the stomach or small intestine.

It can vary in aggressiveness and requires specialized treatment, such as surgery or targeted therapy, based on its size, location, and genetic characteristics.

Small intestinal lymphoma was in the differential diagnosis.
