Patient Data

Gender: Male

Multiple dilated loops of small bowel containing fluid and gas noted throughout the abdomen.

There is narrowing of the cecal lumen with irregular circumferential thickening, which is likely the transition point of partial small bowel obstruction.  The thickening extends into the terminal ileum.

Ill-defined hypodensities are seen throughout the liver, suggestive of metastases.

Case Discussion

Colorectal carcinoma is an important cause of bowel obstruction. This patient presented with a small bowel obstruction due to the location of the tumor. The patient was transferred for right hemicolectomy. 

Histology: mucinous adenocarcinoma
