Adrenal abscess in the neonate.

Adrenal abscess in the neonate is a rare complication of adrenal hemorrhage. The radiographic and clinical findings of 12 previously published cases and two new cases of adrenal abscess in the newborn are presented. Sonography was the most helpful examination in distinguishing a suprarenal lesion from an intrarenal lesion and in demonstrating the morphology of the abscess.
