abstract="The most common neurological injuries associated with roller coaster rides are subdural hematoma and cervical artery dissection. We report two cases of roller-coaster associated subarachnoid hemorrhage (SAH). A 40-year-old healthy man developed a strong, holocephalic headache during a roller coaster ride. SAH Hunt & Hess grade II and Fisher grade 3 was diagnosed. An underlying aneurysm of the anterior communicating artery was successfully treated with coil embolization. A 41-year-old female (smoker, otherwise healthy) experienced a sudden, strong headache and diplopia during a roller coaster ride. A perimesencephalic SAH (Hunt & Hess grade II, Fisher grade 3) was disclosed by a CT scan. No aneurysm was detected on angiography. Both patients were discharged without neurological disability. In conclusion, SAH is a rare but relevant differential diagnosis in cases of acute headache during roller coaster rides. Both aneurysmal and non-aneurysmal perimesencephalic SAH can occur. A combination of mechanical factors and excessive blood pressure rises in vulnerable persons is discussed.<p /> <p>Language: en</p>",
