title: [Ultrasonography in the comprehensive diagnosis and evaluation of   treatment effectiveness in retroperitoneal neuroblastoma in children].
abstract: Neuroblastoma and ganglioneuroblastoma of adrenal (17) and extra-organ (60) origin and retroperitoneal extra-organ neoplasia (18), infrequent in childhood, were identified in 109 children referred to the Institute's Clinic with diagnosis of retroperitoneal tumor. Ultrasound characteristics of retroperitoneal tumors of the sympathetic nervous system and predictive value of ultrasound for involvement of adjacent organs and vessels were defined and classified. Similar criteria for differential diagnosis between retroperitoneal neuro- and ganglioblastoma and rare pediatric retroperitoneal tumors were worked out. Dynamics of evidence in the course of conservative treatment of tumors and the role of ultrasound tomography in evaluating retroperitoneal neuroblastoma were established. Predictive value of sonography, computed tomography and angiography in certain applications was compared.
