Aneurismatic jejunal lymphoma in a 43-year-old female. (a, b, c) Precontrastographic and postcontrastographic axial CT scan show severe circumferential wall thickening (thickening 17 mm), inhomogeneously hyperdense after contrast medium injection, of a jejunal ileal loop (length: 20 cm) located in the left side and left upper quadrant (red circle). Moreover, endoluminal dilatation and air-fluid level inside and enlarged lymph nodes and the surrounding mesenteric fat can be noticed (arrowheads). (d) Infiltration of the left colonic and sigmoid bowel wall (arrow). (e) Thickened bowel walls are entwined with a newly formed lymphomatous mass of the left abdominal wall that infiltrates the left abdominal wall muscles and the superior edge of the left iliac muscle.
