Imaging findings of a twin male neonate with megacystis microcolon intestinal hypoperistalsis syndrome

Megacystis microcolon intestinal hypoperistalsis syndrome (MMIHS) is a rare congenital defect of the bowel and bladder that is especially rare in males. We present a case of MMIHS in a male nonidentical twin neonate who presented with abdominal distention, urinary retention, and hypoplastic bowel. The voiding cystourethrogram included in this report displays rare image of MMIHS in a male urogenital system. The constellation of clinical and imaging findings presented in this case are characteristic of MMIHS and may aid the early diagnosis of male neonates affected by this disease.
