Radiological Features of Gastrointestinal Lymphoma

Figure 5

Abdominal CT scan of ileal and sigmoid lymphoma in a 78-year-old male. Axial CT scan in the portal venous phase shows a non-Hodgkin lymphoma seen as abnormal circumferential bowel thickening of the sigmoid colon ((a) arrow) and of the last ileal loop ((b) and (c) arrowheads). Enhanced lymphomatous small bowel loops (b) represent the halves of a sandwich, enveloping enhanced vessels (the sandwich filling). The patient underwent chemotherapy with marked reduction of the thickening at the follow-up CT scan.
