Duplication of the gallbladder

Objective : to demonstrate a previously unreported variant of gallbladder malformation as an incidental finding. Material and methods . A clinical observation of an elderly patient with no pathological process and a gallbladder malformation is presented. Results . Based on a preliminary examination in a neurological department of a hospital, the patient was suspected of having a peri-vesical abscess or an abscess in the right lobe of the liver. This was evidenced by persistent low-grade fever and the results of instrumental examinations (ultrasound and CT scans of the abdominal cavity). After the treatment of acute cerebrovascular accident, the patient was transferred to the surgical department. An MRI scan of the abdominal cavity suggested a double gallbladder, and a subsequent MRCPG scan confi rmed this diagnosis. Thus, based on the results of the examination, the patient’s development of a perivesical abscess as a source of fever of unknown origin was excluded. The absence of a clinical picture of acute and chronic (calculous) cholecystitis at the time of the additional examination allowed the patient to be discharged without undergoing surgical treatment. Conclusion . The presented case remained diagnostically unclear for a week. The clinical picture was complicated by an acute period of cerebrovascular disorder and the development of idiopathic subfebrile fever, which was compounded by the lack of information from the main diagnostic methods. The final clinical diagnosis allowed us to determine the further tactics and describe a previously unreported variant of gallbladder malformation.
