KW - Retroperitoneal cyst, urothelial histogenesis, mimicking hepatic cyst
AB - Background: Benign retroperitoneal cysts are uncommon. There is a paucity of literature on primary upper
abdominal retroperitoneal cysts of urothelial histogenesis. We report an uncommon presentation of
urothelial cyst clinically mimicking a hepatic cyst.
Case presentation: A 21-year old female patient was admitted with intermittent abdominal pain of 9
months duration diagnosed on radiology as a right hepatic cyst. Laparoscopic resection and pathologic
examination revealed a primary retroperitoneal cyst with a urothelial histogenesis. This is an unusual clinical
presentation of a rare lesion mimicking a hepatic cyst.
Conclusion: This case highlights the unusual anatomic location and the rare occurrence of an upper
abdominal retroperitoneal urothelial cyst.
