Computed tomography (CT) showed an irregular-shaped invasive mass or fluid collection in the right Morrison's pouch, right paracolic gutter, gallbladder fossa, subphrenic space, or abdominal wall. CT and ultrasound revealed gallstones in the granuloma in 3 cases and an abscess in one case. The inflammatory process induced by dropped gallstones may mimic peritoneal malignancies. Awareness of cholecystectomy and the detection of gallstones in the lesion are essential for the diagnosis of dropped gallstones., Journal Article}, pages = {1480--1484}, title = {Foreign-body granulomas and abscesses caused by dropped gallstones after cholecystectomy : Four cases diagnosed with multimodality imaging.}, volume = {15}, year = {2020} }
