Prenatal adrenal hemorrhage confirmed by postnatal surgery.

A case is reported of massive adrenal hemorrhage in a newborn with evidence of bleeding in utero. A large cystic mass noted on prenatal ultrasonography at 20 weeks of gestation was followed by serial examinations until birth at 38 weeks of gestation. Postnatal evaluation included abdominal sonography, diethylenetriaminepentaacetic acid renal scan, voiding cystourethrography and abdominal plain film. Surgical exploration confirmed massive adrenal hemorrhage.
