Successful renal transplantation in a 3-month-old infant

Abstract

as in our first patient. Such a well-defined purely echolucent mass probably represents a central hematoma of the adrenal gland. Our pat ient 2 had a Complex mass with both cystic and solid elements; this pattern is consistent with adrenal hemorrhage and adrenal necrosis, a combination found in 15% of hemorrhagic adrenal glands at autopsy, 3 but it could also represent adrenal hemorrhage with clot. The possibility that neonatal neuroblastoma could cause these ultrasonic findings underlines the necessity for obtaining careful f011ow-up in such patients, although in neonatal neuroblastoma the solid elements predominate over the cystic. In addition, the clinical history, rapid resolution of the mass, and lack of any symptoms or signs of neuroblastoma made this diagnosis unlikely in Patient 2. The value of ultrasonography is emphasized because it is safe, simple, and noninvasive. Fol low-up studies with abdominal ultrasound provide an easy method to follow the resolution of adrenal hematomas.
