A Rare Case of Perinatal Intrarenal Neuroblastoma.

Perinatal neuroblastoma is the most common solid malignant tumor in infancy which comprises one fifth of all neuroblastomas. Most of them are of adrenal origin and extra-adrenal neuroblastoma is uncommon. We present a rare case of perinatal intrarenal neuroblastoma in a neonate who presented with an incidentally detected abdominal mass. These tumors cause diagnostic and therapeutic dilemma because of its uncommon location. Although very rare, neuroblastoma should be considered in the differential diagnosis of perinatally detected renal tumors.
