During two years (1994-1996) in Radiology Department of Pediatric Hospital in Cancer Research Center of Russia there were made 336 initial ultrasound examinations in children which had abdominal and retoperitoneal tumors or limphoprolipheratic desease with lesions of the area. Subjective mistakes related to unsufficient knowledge of oncopathology in children and consequently this led to wrong interpretation of monographic images. In most cases children with retroperitoneal neurogenic tumors closely linked with kidney, but clearly separated from it have been sent to pediatric hospital with Wilm's tumor diagnosis. In two patient paravertebral retroperitoneal situated neuroblastomal of small size was assumed to be hypoplastic distopic kidney and in one case ablated in Moscow children surgery hospital. In one 5- year old patient doublesided neuroblastoma situated in lower part of kidney with extrarenal growth was erroneously reckoned to be hydronephrosis of both kidneys. Objective mistakes have been caused by complexity of defining of the primary localization of extensive neoplasms growing throw nearest tissues or by non-typical sonographic symptoms of the tumor. Unusual ultrasound pictures has become the reason of incorrect assumed diagnosis in two patients. In first case the left kidney of six- years old girl, totally affected by the vast /14/10/17 am/ Wilm's tumor was initially assumed to be hypertrophic spleen. Gathering system visualized in the form of stretched hypoechogeneous zone and it looked like spleen vein. Further examination (CT, anglography) permitted to get correct to get diagnosis. In second case of retroperitoneal neurblastome with paracaval and paraaortal metastatic lymphonoduses it was suspected to be lymphoproliferatic disease.
