An antenatal appearance of megacystis-microcolon-intestinal hypoperistalsis syndrome.

[megacystis-microcolon-intestinal hypoperistalsis syndrome]

We herein present a megacystis-microcolon -intestinal hypoperistalsis syndrome (MMIHS ) case followed by ultrasound (US ) examinations before birth . During the prenatal US examination of a 34 -year -old woman , an enlarged bladder with bilateral hydronephrosis and hydroureter of the fetus were detected . The amniotic fluid was normal in the second trimester but polyhydramnios was observed in the third trimester . A female baby was born by cesarian section weighing 2632 g . Imaging studies detected an enlarged bladder with bilateral hydronephrosis , hydroureter and microcolon . Laparotomy on the 9 th day confirmed a short small bowel with caliber change and the existence of ganglion cells and plexus of the nerve in the intestine . These findings correlated with the previously reported characteristics of MMIHS . An enlarged bladder in the second trimester and polyhydramnios in the third trimester have been reported in many cases of MMIHS . These findings may thus help to accurately diagnose MMIHS before birth .
