Neuroblastoma is one of the most common neonatal tumors. It involves children in early infancy
and originates from neural crest cells of the adrenal gland medulla or sympathetic glia. We report
an unusual case of congenital poorly differentiated neuroblastoma with multiple metastases in the
brain and cerebellum. The biophysical profile showed a prominent polyhydramnios at 25.3 weeks
