We report the delayed diagnosis of glioblastoma in a 65-years old female with recent history of subarachnoid hemorrhage. In the literature are described few similar cases: we briefly discuss the management in the rare occurrence of a double neurosurgical disease. Keywords: Glioblastoma; cerebral tumor; diagnosis; subarachnoid hemorrhage; aneurysm; hydrocephalus.
