간 전이가 동반된 Stage IV-S 신경모세포종에서 부신절제 후 간 전이의 자연소실 - 1예보고 -

Prenatally diagnosed neuroblastomas have been reported in increasing numbers over the past several years. The vast majority are in favorable stages of the disease (stage I, II, IV-S). The authors experienced one case of stage IV-S neuroblastoma of the adrenal gland with liver metastasis, which regressed spontaneously after removal by adrenalectomy. This patient was noticed to have an abdominal mass at prenatal ultrasonography performed at 36weeks of gestation. This tumor was a neuroblastoma of the left adrenal gland with multiple liver metastases. Left adrenalectomy and liver biopsy were performed at 3 months of age. Thirty-eight months after surgery, an MRI demonstrated that the hepatic metastatic lesions had completely regressed without chemotherapy or radiation.
