title: Sonography of neuroblastoma.
abstract: Sonograms of 21 children with neuroblastoma were reviewed with attention to the following sonographic criteria: size, location, internal echo pattern, anechoic areas, and margination. Fourteen primary tumors were evaluated before therapy. All tumors were heterogeneously echogenic; all had poorly defined margins. Tumor calcification was identified in three, and 10 of 14 primary tumors contained discrete anechoic areas ranging from 0.5 to 4 cm in diameter. The average greatest dimension of primary tumor masses was 7.7 cm.
