Selected axial computed tomography images demonstrated (a) an eccentric thickened wall of the distal transverse colon (black arrow) (b) with a focal, walled-off intra-abdominal fluid collection, extending from the wall of the transverse colon to the left anterior abdominal wall (white arrow). Invasion and thickening of the transversalis and rectus abdominis muscles was noted (white arrow). There was associated increased density and stranding in the pericolic fat and adjacent abdominal wall fat from the inflammation (arrowhead).

Helical CT images were acquired from the lung bases to the symphysis pubis with multiplanar reformats, post intravenous and oral contrast administration (Figures 1 and 2).
Selected coronal (a) and sagittal (b) images of the patient demonstrates the thick-walled distal transverse colon and associated walled-off collection closely related to normal appearing small bowel loops (white arrows).

Helical CT images were acquired from the lung bases to the symphysis pubis with multiplanar reformats, post intravenous and oral contrast administration (Figures 1 and 2).
Multiple sections were sampled, all of which revealed soft tissue, consistent with inflammatory granulation tissue, and an abscess.

Upon opening the large bowel, gross pathology indicated a mass lesion (Figure 3).
A small opening was identified in the bowel wall (arrow).

A small opening was identified in the bowel wall and further sectioning revealed a fish bone (Figures 4 and 5).
Further sectioning in this area revealed a 3 cm fish bone (arrow).
