From: Non-neoplastic hepatopancreatobiliary lesions simulating malignancy: can we differentiate?
A 65-year-old male with a history of colon cancer in remission for 7 years underwent a follow up CT. He was completely asymptomatic at the time of the CT scan. He also has a remote history of laparoscopic cholecystectomy 5 years before. Axial plane postcontrast CT image demonstrates a complex looking cystic mass in the liver capsule (arrows) suggestive for a tumor implant. Also note is made of a small solid nodule in the left upper quadrant (arrowhead). Surgical excision confirmed malignant implant in the left upper quadrant and an inflammatory pseudomass in the liver capsule due to a dropped gallstone.
