[A case of ruptured congenital neuroblastoma caused by birth injury].

A 3,900 g full-term male newborn had to be operated on for suspected intraabdominal bleeding due to birth injury. Intraoperatively, a tennis-ball sized, ruptured tumor between right kidney and liver was found to be the source hemorrhage. The tumor was excised in toto. The newborn died 25 hours after the end of operation from protracted shock and renal failure. Post mortem examination did not reveal further malformations or metastases. Histological diagnosis: congenital neuroblastoma of the adrenal gland. Improved antenatal ultrasound diagnosis followed by cesarian section could help to improve the prognosis in such cases in future.
