Prenatal diagnosis of neuroblastoma by sonography.

Herein we report the first case in the literature in which a neuroblastoma in a fetus was recognized before birth and its growth could be observed. The diagnosis was made by ultrasonography. Other helpful diagnostic procedures in prenatal diagnosis are: determination of catecholamines, sonographic examination of the placenta, and search for metastases. As more and more centers perform ultrasound examinations routinely in pregnancy, similar findings such as fetal tumors or congenital malformations are to be expected more frequently.
