ВОЗМОЖНОСТИ МУЛЬТИСПИРАЛЬНОЙ КОМПЬЮТЕРНОЙ ТОМОГРАФИИ В ДИАГНОСТИКЕ ЗАБРЮШИННЫХ ОПУХОЛЕЙ У ДЕТЕЙ

Abstract

The goal of this work was the assessment of capability for multidetector computed tomography (MDCT) in the diag-nostics of retroperitoneal tumors in children. We studied the results of multidetector computed tomography of 63sick children (36 boys (58%) and 27 girls (42%)) between the ages of 1 month to 16 years, from 2012 to 2015. The aver-age age of the patients was 4.9±4.5 years, with a predominance of boys (2:1.4). Among retroperitoneal tumors in children most often we found neuroblastoma (50.8%): in 38.1% it was detected in boys, in 12.7% – in girls (p<0.05). Nephroblastoma was detected in 10%, the other retroperitoneal tumors accounted for 40%. In 56% neuroblastoma was located at the upper level of retroperitoneal space. In 44% tumors localized in para-aortic area, in paravertebral space or in the pelvis. Neuroblastomas on MDCT scans were presented by heterogeneous formations, unevenly accumu-lating contrast. In 62% of cases we detected calcifications, in 19% we observed cysts and in 56% of cases there were metastatic involvements detected. Thus, the MDCT is a method able to accurately specify the localization of the tumor, to clarify the character and volume of destruction, to determine the exact size of a tumor and its relationship with the surrounding tissues, as well as to reveal metastatic lesions in the abdominal cavity and in other organs.
