There is an ill-defined, rounded to lobular soft tissue opaque structure in the mid-ventral abdomen caudo-dorsal to the liver. There are intestinal segments superimposed with this structure on all views. The cranial pole of the left kidney is rounded and enlarged compared to the caudal pole. The unobscured margins of the right kidney are normal. The spleen and urinary bladder are normal. No free peritoneal gas is identified. T
- Abdominal mass may be intestinal or lymph node in origin. Moderate hepatomegaly, soft tissue mass and mild peritoneal effusion raises concern for a diffuse infiltrative neoplasia (lymphomatosis or carcinomatosis). Abdominal ultrasound is recommended for further evaluation.
Jejunal wall mass with regions of ulceration, multifocal sites of asymmetric jejunal and colonic wall thickening (with a focal region of loss of colonic wall layering), bilateral renal nodules/small masses, and nodular hepatomegaly with hepatic nodules/small masses; these findings are most consistent with disseminated neoplasia, with primary consideration given to lymphoma.
