Prenatal sonographic diagnosis of adrenal neuroblastoma

Neuroblastoma is the most frequent extracranial solid tumor in childhood, b ur it is seldom diagnosed prenatally. We report a case of adrenal neuroblas toma identified at 39 weeks' menstrual age and successfully Treated by post natal surgery and chemotherapy. Sonography revealed a hyperechoic mass in t he right upper quadrant of the fetal abdomen associated with hydramnios and hydronephrosis. Two days after delivery, the tumor was resected. No metast asis was identified. The infant received 6 cycles of chemotherapy, and at 2 years of age she was well, with no signs of recurrence. (C) 2001 John Wile y & Sons, Inc.
