title: Inflammatory pseudocyst associated with trisomy 21 and Hirschsprung's disease.
abstract: A 15-month-old black male with trisomy 21 and Hirschsprung's disease developed an inflammatory abdominal pseudocyst 1 month after Swenson pull-through repair. Although abdominal pseudocyst associated with ventriculoperitoneal shunts, peritoneal dialysis catheters, meconium peritonitis, and pancreatitis have been reported, this is the first report of a pseudocyst developing 1 month after a surgical repair of Hirschsprung's disease.
