The megacystis-microcolon-intestinal hypoperistalsis syndrome is a con
genital disorder characterized by urinary bladder distension and hypop
eristalsis throughout the entire gastrointestinal tract. We present a
new case with the typical clinical, radiological, and pathological fin
dings of the syndrome. The diagnosis should be suspected in a patient
who presents clinically with intestinal obstruction and urinary retent
ion, and confirmed with imaging studies, including abdominal plain fil
ms, urinary tract ultrasonography, and contrast studies of the colon a
nd the bladder. The prognosis is generally very poor. Our patient died
secondary to sepsis on day 5 of Life.
