ABSTRACT
Objective To investigate CT features of pediatric mediastinal neuroblastoma.Methods The CT performance of pediatric mediastinal neuroblastoma confirmed by clinical and pathology in 17 cases were retrospectively analyzed.The tumor growth pattern,size,density,degree of enhancement,invasion to the surrounding tissues and metastatic characteristics were observed,and the results were compared with pathological analysis.Results Among the 17 cases,2 were at the right posterior upper mediastinum,3 at posterior right middle and upper mediastinum,3 at the posterior right middle and lower mediastinum,1 at the posterior right lower mediastinum,3 at the posterior left middle mediastinum,3 at the posterior left middle and lower mediastinum,1 at the posterior left lower mediastinum,and 1 at bilateral posterior middle and lower mediastinum.The average tumor size was 6.3 ×4.3 cm,ranging from 2.3 ×2.0 cm ~ 12.6 ×4.0 cm.CT plain scan showed 8 cases with clear boundary and 9 case without clear boundary.13 cases were with inhomogeneous density and 4 cases with homogeneous density.8 calcification of grainy or strip was found in the tumor.10 cases were with pleural thickening and 5 cases with pleural effusion.6 cases were with tracheal or main bronchial compression,4 with cardiac compression,7 with pulmonary artery compression,and 1 with descending aorta compression were found.6 cases were with tumors crossing the midline,5 with intervertebral foramen growth,3 wrapped around the aorta,3 with rib attack damage,2 with rib compression deformation,2 with thoracic invasion,and 1 into the upper abdomen.10 cases were with mediastinal lymph nodes enlargement,10 with bone metastasis,4 with cervical lymph nodes enlargement,1 with liver metastasis,and 1 with cerebral metastasis.Enhanced CT scan was performed in 14 cases11with inhomogeneous enhancement,and 3 with homogeneous enhancement.The average CT value of the 3 mild enhancement was 36 HU,ranging from 20 to 56 HU.The average CT value of the 8 moderate enhancement was 53 HU,ranging from 36 to74 HU.The average CT value of the 3 marked enhancement 72 HU,ranging from 56 to 88 HU.7 punctate vessels and 6 polycystic changes were found in the tumors.Conclusions Mediastinal neuroblastoma in children are with certain characteristics.CT findings with clinical manifestations can make a definite diagnosis.
