Neural tumors of the thorax: subject review from the AFIP

160 tumors of neural origin occurring in the thorax were analyzed. The major histological features of schwannoma, neurofibroma, neuroblastoma, ganglioneuroblastoma, ganglioneuroma, and paraganglioma are described. Radiological analysis emphasized shape and location. Calcification was relatively uncommon but may be specific. The comparatively low figures on incidence of rib and vertebral abnormalities might be increased by special studies, including vertebral tomography. Evidence of local spread such as pleura-based nodules and pleural effusion constitutes evidence of malignancy. Age may be the most important clinical parameter for distinguishing between histological types.
