A. Hemorrhage into glioblastoma = Although glioblastoma multiforme brain tumors can occur at almost any age, they're most common after 50 years of age. (& also CT didnīt show the tumor)
B. Hypertensive hemorrhage = very rare at age 17
C. Occlusion of MCA = very rare at age 17
D. Ruptured Arteriovenous malformation
E. Ruptured saccular aneurysm = Saccular aneurysms are situated in the anterior circulation in 85-95% of cases and frequently rupture into the subarachnoid space
