A Rare Case of Hydronephrotic Multicystic Dysplasia with Ipsilateral Upper Segmental Megaureter in Adults

Multicystic dysplasia in adults is a rare entity. It may present as a mass, with pain, or be detected incidentally on imaging. Here, we present a case of hydronephrotic multicystic dysplasia with ipsilateral upper segmental megaureter in an adult female patient. To the best of our knowledge, this is the first such case described in the English literature.
