Purpose: The choledochal cyst is a rare surgical entity due to an anomaly of the bilio-pancreatic junction, which manifests itself mainly during childhood and often revealed by a complication. Imaging plays an important role in the positive diagnosis, allows to analyze the malformation of the main bile duct and to classify it according to the classification of Todani. The aim of our work is to show the contribution of imaging in the diagnosis of this disease in Pediatric Population and its complications. Methods and Materials: This is a retrospective descriptive study of 19 case reports carried out between 2013 and 2020 in the Pediatric radiology and Child Surgery departments at the mother and child hospital at the University Hospital MOHAMED VI. Results: The average age of our patients was 5 years, predominantly female. Abdominal pain was the most common clinical sign. All patients were examined by ultrasound, 11 cases had abdominal CT with injection of contrast agent, while a bili-MRI was performed in 7 patients. These examinations allowed us to objectify a cystic dilatation of the bile duct classified type I according to Todani in 80% of cases, and a type IVa in 20% of patients. Treatment consisted of a resection of the cyst with hepaticojejunal anastomosis associated with cholecystectomy, the postoperative outcome was good. Conclusion: Medical imaging plays an essential role in the diagnosis of cystic dilatations of the bile duct. Bili-MRI is the exam of choice that allows accurate biliary mapping, avoiding the use of invasive opacifications.
