Brief report

Background: Adrenal hemorrhage (AH) is a relatively uncommon condition in neonates. This study aimed to review the clinical, laboratory and ultrasonographic findings of AH in newborns. Methods: The medical records of 13 newborns with AH who had been admitted to our neonatal intensive care unit were retrospectively reviewed. Results: Of the 13 newborns with AH, 8 (62%) were term and 10 (77%) were male babies. Clinical presentations included neonatal jaundice (85%), paleness and/or flank mass (38%), discoloration of the scrotum (15%), and hypotonia/lethargy or hypotension (8%). Five newborns had anemia and four had adrenal insufficiency. Adrenal insufficiency was observed in 80% of the premature infants with AH. AH occurred on the right side in 9 patients (69%). The most predisposing cause of AH was disseminated intravascular coagulation secondary to sepsis or perinatal hypoxia in preterm infants, and large for gestational age in term infants. Ultrasonography (USG) revealed a hypoechoic mass in 7 newborns (54%), a mixed solid-liquid mass in 5 (38%), and an echogenic mass (8%) in 1. Hemorrhage disappeared within 8.6±4.5 (4-16) weeks. Conclusions: AH occurs in the newborns with unexplained jaundice. Adrenal insufficiency is more frequent in preterm than in mature infants. Abdominal USG is required to determine AH in a newborn with swelling and bluish discoloration of the scrotum. Serial USG is the best modality for monitoring AH to prevent unnecessary surgery.
