Hydrometrocolpos and Post-axial Polydactyly Complicated With Acute Intestinal Obstruction and Hydroureteronephrosis.

This report presents a case of a one-month three-day-old full-term female infant with hydrometrocolpos (HMC) and post-axial polydactyly whose first clinical sign was acute intestinal obstruction and hydroureteronephrosis, caused by compression of the structures due to the increasing size of the cystic-like pelvic mass. This is the first report of HMC with post-axial polydactyly complicated with acute intestinal obstruction in Peru. It raises importance on prenatal diagnosis, management and complications of HMC.
