Presentation

Colicky abdo. pain 8 days. No stoma output since 10 days ago. Hx of stage IV uterine cancer with bowel involvement, resected 3/12. Examination - distended + tender.

Patient Data

Age: 61
Gender: Female
Modality: CT

Large low attenuating (18HU), cystic appearing mass in the lower abdomen extending into the pelvis ?compressing the urinary bladder

No abnormality in the retroperitoneum. Ureters difficult to trace to exclude tied of ureters but unlikely as there is no hydroureter/hydronephrosis.

Dilated small bowel loops, no obvious transition zone visible, likely in proximal ileal loops.

Case Discussion

Given that the cystic mass is homogeneous and low attenuating, likely causes are postoperative seroma or a urinoma.
