Megacystis-microcolon-intestinal hypoperistalsis syndrome: a case report

Megacystis-microcolon-intestinal hypoperistalsis syndrome (MMIHS) is a rare congenital disorder characterized by a dilated, non-obstructive urinary bladder and hypoperistalsis of the gastrointestinal tract, which is considered lethal. About 90 patients have been reported, predominantly female. We present the case of a female newborn with MMIHS in whom antenatal ultrasound was suggestive for the diagnosis, which was confirmed after delivery. Diagnostic features by antenatal ultrasound are described.
