Core tip: Gallstone abscess resulting from spilled gallstones is a rare complication following laparoscopic cholecystectomy. We report a rare presentation of gallstone abscess due to spilled gallstones following laparoscopic cholecystectomy, mimicking a retroperitoneal sarcoma in a 59-year-old male. Recognizing the patient information about a history of laparoscopic cholecystectomy and sharing the patient information with radiologists can make an accurate diagnosis and avoid misinterpretation when the diagnosis is equivocal in radiologic imaging. Clear documentation of gallbladder perforation and gallstone can help with diagnosis of the complication and for correct management. Five noteworthy features are discussed in this paper.
