Incidental finding of choledochal cyst in a pregnant woman: case report

Introduction:Choledochal cysts are a rare congenital anomaly of non-defined etiology, commonly diagnosed in childhood, whose main manifestations are abdominal pain, jaundice, and a palpable mass.Although magnetic resonance cholangiography is the gold standard for diagnosis, incidental findings have been increasing due to the extensive use of imaging studies. Case presentation: A 25-year-old woman with an incidental finding of a choledochal cyst (Todani Ia) by prenatal control ultrasound, being managed with resection of the cyst and hepatojejunal Roux-Y anastomosis, leaving a remnant that warrants surveillance by the risk of malignancy. Conclusion:The relevance of this type of cases is knowing about their existence, having a high index of suspicion and being able to carry out a complete diagnostic approach for adequate surgical planning.
