Intramedullary spinal neurinomas

E XTRAMEDULLARY spinal neurinomas are a frequent occurrence, but the intramedullary variety is very rare in patients not presenting signs of yon Recklinghausen's disease. Only 16 such c a s e s 2,s,10-13,15-1s,20,21,23,25 have been reported to date. This study describes two cases of intramedullary neurinoma found in a series of 145 patients with spinal neurinomas and 173 intramedullary spinal gliomas operated on at the Institute of Neurosurgery, University of Rome, from 1955 to May, 1981. The relevant literature is reviewed.
