Gallbladder agenesis is a rare biliary anomaly which can be important for patients complaining of chronic abdominal pain. Gallbladder agenesis can mimic cholecystitis by causing recurrent upper abdominal pain and tenderness. In a significant number of patients with gallbladder agenesis, unnecessary surgical procedures are performed because of the misdiagnosis. The morbidity of the disease can reduce, since the correct diagnosis of gallbladder agenesis decrease unnecessary surgical procedures. The diagnosis can be established with performing ultrasound and Magnetic resonance cholangiopancreatography (MRCP) examination. We reported a case of a young patient suffers from recurrent abdominal pain and diagnosed with gallbladder agenesis.
