Abstract

Neuroblastoma is the most common solid malignancy in childhood. However, a neuroblastoma presenting as bilateral and multifocal is very rare. A male newborn weighing 2.7 kg was born by normal vaginal delivery at 39 weeks' gestation to a 27-year-old mother who had a normal pregnancy. He was in good condition at birth but presented palpable masses in the both upper abdomen and both side of the neck. Ultrasound examination showed the lesions to be 3 Ã— 3cm sized calcified mass in right suprarenal area and 5 Ã— 3cm sized homogenous mass in left suprarenal area. The abdominal mass was also examined by computed tomography with similar findings. With the impression of bilateral neuroblastoma or metastatic spread, the laparotomy was performed on the 13th day of life. Frozen section of biopsy of the left neck mass was obtained, which showed neuroblastoma. Intraoperative findings revealed bilateral adrenal masses which were distinct and anatomically separate. Bilateral adrenalectomy was accomplished and the initial postoperative course was unevenful. The patient was discharged for hopeless and expired at age 45 days. We present bilateral adrenal neuroblastoma considered to be simultaneous occurrence rather than metastases from one site to another.
