Cystic neuroblastoma.
In the newborn, cystic masses of the adrenal gland are unusual findings and most are secondary to hemorrhage. We present a patient with a clinical history typical for adrenal hemorrhage who was found to have a thick walled cystic adrenal mass on both physical and ultrasound examination. During evaluation the mass decreased in size, but vanillylmandelic acid (VMA) and homovanillic acid (HVA) levels were elevated. Laparotomy and left adrenalectomy confirmed the diagnosis of a cystic neuroblastoma. Adrenal cyst, adrenal abscess, and cystic neuroblastoma are all rare entities in the newborn. We recommend that all cystic masses of the adrenal be evaluated by urinary VMA and HVA and that the possibility of cystic neuroblastoma be kept in mind when an adrenal cystic mass is followed nonoperatively.
