Purpose or Case Report: Megacystis microcolon hypoperistalsis syndrome (MMIHS) also known as Berdon syndrome is a rare genetic disorder with a poor prognosis characterized by hypoperistalsis of the bladder and bowel. When expediently diagnosed and managed, survival can be extended. The radiologist plays a role in the initial diagnosis and recommending further imaging based on the known constellation of findings in collaboration with the pediatric surgeon and pediatric urologist. The radiologist could be the first to appreciate characteristic findings and suggest the possibility of this syndrome.

The purpose of this educational exhibit is to describe the imaging characteristics of Berdon syndrome from the fetal stage to early childhood with an emphasis on 1) main radiologic findings, 2) helpful imaging features to differentiate Berdon syndrome from other similar conditions, 3) appropriate imaging studies to assist in supporting the diagnosis, and 4) clinical findings, management, and outcome. We will review 9 cases and their corresponding imaging.
