Twenty-five patients with glioblastoma multiforme were autopsied at our institution in 7 years. Spinal cords were examined in 20 and 5 were found to have spinal leptomeningeal metastases. Clinical and neuropathological findings of these 5 patients are presented and factors possibility influencing such spread are analyzed. ⋯ These findings are of little significance at present with our poor success at control of the primary lesion. Frequency of involvement of the spinal subarachnoid space will be significant, when we are able to better treat the primary tumor. Knowledge of the significant possibility of this phenomenon will allow earlier and more frequent clinical diagnosis.
