title: Megacystis-microcolon-intestinal hypoperistalsis syndrome. Antenatal appearance in two cases.
abstract: Two cases with severe congenital megacystis-microcolon-intestinal hypoperistalsis syndrome (MMIHS) are presented. This is a rarely encountered syndrome in neonates and 45 cases have earlier been reported. The disease is usually lethal and it now seems clear that MMIHS is an autosomal recessive disorder. The enlarged bladder, typical of this syndrome, is however easy to define by ultrasound, sometimes even in early pregnancy. The concomitant finding of a dilatation of the urinary tract and the absence of oligohydramnios may lead the physician to suspect the diagnosis. Because of the information available from sonography, appropriate investigations can be undertaken immediately after delivery. Prenatal ultrasound examination in subsequent pregnancies is recommended.
