Gallbladder duplication results from a rare abnormality of embriogenesis1 and is twice as common in women as in men2 .The signs and symptoms of double gallbladder cholecystitis are the same as those of single gallbladder cholecystitis: strong pain in the epigastric region and right hypochondrium, which may irradiate to the back and be accompanied by nausea and/or vomiting, Murphy positive sign, and pain on palpation of these regions; plastron may also be present3 . For this reason, many cases are still diagnosed intraoperatively, making surgery difficult and increasing the possibility of biliary tract injury. We report the case of a female patient with epigastric and dorsal pain for 4 days, which worsened with the ingestion of salty and fatty foods and was accompanied by nausea and vomiting. Physical examination showed a positive Murphy sign. A complete abdominal ultrasound examination showed gallbladder duplication, both lithiasic. Magnetic resonance cholangiography confirmed the duplication of the gallbladder and cystic ducts, with a single main biliary tract and acute lithiasic cholecystitis in both gallbladders. A laparoscopic cholecystectomy of both vesicles was performed without complications, and the patient was discharged 3 days after the procedure.
