Megacystis-Microcolon-Intestinal Hypoperistalsis Syndrome.

We report a case of megacystis-microcolon-intestinal hypoperistalsis syndrome (MMIHS) in a newborn female infant who presented with an abdominal mass, absent bowel sounds, and feeding intolerance with bilious emesis. MMIHS is a rare congenital bowel and bladder defect requiring surgery and chronic total parenteral nutrition in an attempt to sustain life. With few exceptions, it is predominately fatal within the first six months of life. We describe the relevant clinical and radiologic findings with ultrasound correlation of this case followed by a brief review of literature included in the discussion.
