The diagnosis of abdominal neuroblastoma: relative roles of ultrasonography, CT, and MRI.

Abstract

Abdominal neuroblastoma is reviewed in terms of its diagnosis, including in utero, at birth, and through infancy into childhood. Age at diagnosis remains the best predictor of survival, with infants under 1 year of age having almost 100% cure. Ultrasonography and magnetic resonance imaging (MRI) are the recommended diagnostic modalities to stage the abdominal primary, although computed tomography (CT) (including myelography) is still widely and efficiently used. Examples are given of each stage.
