Late Port Site Metastasis from Occult Gall Bladder Carcinoma After Laparoscopic Cholecystectomy for Cholelithiasis: The Role of 18F-FDG PET/CT

  • 1Department of Nuclear Medicine and PET/CT, Eastern Diagnostics India Ltd, 13C, Mirza Ghalib Street, Kolkata 700016, India.


Late port site metastasis of gall bladder carcinoma (GBC) after laparoscopic cholecystectomy is a rare finding. Rarer still is such a presentation where the GBC remained occult at histopathology. 18F-flurodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) can play an important role in this setting by supporting the diagnosis of port site metastasis, by demonstrating additional sites of metastasis, if any, and by ruling out any other primary site. We here present two such patients with late port site metastasis of occult GBC after laparoscopic cholecystectomy for cholelithiasis and discuss the role of 18F-FDG PET/CT in this setting.
