“…However, cholesterol‐based stones (which are non‐calcified) may not be visible on CT until long‐standing, chronic, tissue reaction has occurred 2,4 . MRI and ultrasound can be used to corroborate the diagnosis, but are also often difficult to interpret 1,3,4,5 . Similarly, FDG‐PET CT frequently shows low avidity of retained gallstones, which can also be the case with peritoneal carcinomatosis 9 .…”

“…Consequently, when calcified peritoneal nodules are discovered, peritoneal metastases from appendiceal, colorectal, gastric or ovarian cancer should be ruled out 1,2 . Accordingly, there are rare reports of retained gallstones discovered on diagnostic laparoscopy after suspicion of peritoneal carcinomatosis 3,5,6,7 . Dropped gallstones have the potential to slowly erode through tissue planes and deposit in the retroperitoneum, peritoneum of the abdominal wall, or even the pleural cavity 4 .…”

“…2,3,4 This contrasts with open cholecystectomy, where retained stones are rare. 5,6,7 Most patients remain asymptomatic (>90%), 3,5,8 however, abscess formation, chronic granulomas and adhesive bowel obstruction can occur months or even years later. 6 The differential diagnosis is broad, but includes calcified lymphadenopathy from tuberculosis, lymphoma, sarcoidosis or amyloidosis, 3 'sheet-like' calcifications from peritonitis or peritoneal dialysis, 1 peritoneal carcinomatosis and of course retained gallstones.…”

A 67-year-old woman was referred to a peritoneal malignancy centre with suspicion of peritoneal carcinomatosis from unknown primary. She reported a two-year history of intermittent rectal bleeding and mild upper abdominal pain. Her past history included a myocardial infarction, hysterectomy and laparoscopic cholecystectomy 25 years prior. Histopathology and operation reports from her previous surgeries were unavailable. Computed tomography (CT) of the abdomen and pelvis demonstrated multiple calcified nodules in the perihepatic, omental and right paracolic regions, suggestive of peritoneal carcinomatosis (Fig. 1). Physical examination revealed a soft, non-tender abdomen with no palpable masses, and an unremarkable digital rectal examination.
