Abstract
The authors report the case of a man who underwent cranial surgery for the removal of a craniopharyngioma using a right pterional approach. Three months later, he developed a right-sided temporal glioblastoma. The presentation is suggestive of a causal relationship between surgery and the development of a malignant glial tumor.
