Background: Malformations related to the gallbladder are uncommon, with an incidence lower than 0,1%.
The majority of them are asymptomatic, however when symptoms appear are non-specific with a similar
presentation to biliary colic.
Methods: We report a case of a 29-year-old woman with persistent upper right abdominal pain and no
visualization of the gallbladder in the ultrasound (US), CT scan or in the magnetic resonance
cholangiopancreatography (MRCP).
Results: A laparoscopic exploration was performed due to persistent abdominal pain which confirmed an
hypoplasic gallbladder. After cholecystectomy, symptoms were relieved. Herein we propose a decisional
algorithm when suspecting a gallbladder with agenesis or hypoplasia.
Conclusion: Surgeons need to take into consideration congenital anomalies of the gallbladder. Performing
imaging techniques is important in order not to misdiagnose hypoplasia.
