| Abstract: | The authors present the first reported case of a glioma associated with a right posterior cerebral artery (PCA) aneurysm. A 37-year-old male underwent craniotomy and total removal of the glioma, which appeared, according to encephalographic findings, to be responsible for the initial symptom of loss of consciousness. The risk of craniotomy-induced bleeding from the aneurysm was thought to be low, since it was unruptured and was packed with coagulum. However, subarachnoid hemorrhage due to rupture of the PCA aneurysm occurred just after craniotomy, and clipping was performed 15 days after the first operation. |
