[Adrenal hemorrhage in perinatal period--a case report].

The incidence of adrenal hemorrhage in perinatal period is 0.2-0.5%. Prenatal diagnosis is rare. In most cases, hemorrhage is found during extensive diagnostic workup in a life-threatened or seriously sick newborn. We present a case of a female neonate born at term with suspected cystic intraabdominal mass already in the 32nd week of gestation. After delivery abdominal sonography was done and found an inhomogeneous formation above the upper pole of the right kidney. On magnetic resonance imaging (MR) this formation was described as an expansive lesion in the lodge of the right adrenal gland, measuring 3.8 x 2.8 x 3.5 cm, which corresponded to the bleeding from the adrenal gland. Extensive differential diagnostic evaluation excluded other diseases, especially malignant. From the birth during the perinatal period the child had no clinical manifestation. Regular ultrasound monitoring showed the resolution of the described formation, until its complete disappearance at the age of two months.
