Presentation
Known case of left colonic carcinoma operated 1 month ago and had resection of the tumour with end-to-end colo-colic anastomosis.
Patient Data
Well-encapsulated left subphrenic ovoid hypodense structure containing air-bubbles with peripheral enhancement. A mass effect is noted on the spleen with mild reactive left-sided pleural effusion.
Thickening of the left anterior renal and lateroconal fasciae with fat stranding of the anterior pararenal space as well as a small adjacent fluid collection.
No abnormal thickening at the colo-colic anastomosis.
A small accessory spleen is noted.
The rest of the CT scan exam is unremarkable.
Case Discussion
The CT feature in a patient with a history of surgery is most consistent with a gossypiboma which was confirmed at surgery (infected gossypiboma).
