According to previous reports, pseudoaneurysms that are concomitant with a dural arteriovenous fistula (dAVF) are associated with penetrating trauma, blunt trauma, and skull fractures. Moreover, dAVFs between the inferolateral trunk of the internal carotid artery and middle cerebral vein are a rare disease manifestation. Pseudoaneurysms concomitant with dural arteriovenous fistulas (dAVF) are rare and traumatic pseudoaneurysms with dAVF typically developed slowly with less rebleeding than isolated traumatic aneurysms. ⋯ The traumatic pseudoaneurysm was completely obliterated by surgical clipping, followed by decompressive craniectomy and postoperative coma therapy with propofol. Resulting from these surgical and postoperative treatments, 56 days after the operation the patient recovered fully and did not present any neurologic deficits.

Intracranial osteoma arising from nonosseous tissue and surrounded by brain parenchyma is extremely rare. We report an intracranial osteoma surgical case with no heterotopic ossification. ⋯ In this rare surgical case of subarachnoid osteoma, comprehensive preoperative neuroradiologic examinations, accurate surgical management of adjacent brain tissue, and vessel protection were the cornerstones of successful resection.

Vasospasm developing after subarachnoid hemorrhage (SAH) is an important cause of mortality and morbidity. Lutein is a carotenoid with antioxidant and anti-inflammatory properties. The aim of present study was to investigate effects of lutein on the basilar artery and nerve tissues. ⋯ Lutein was found to have a positive effect on width of the basilar artery lumen area. Therefore, positive effects of lutein on vasospasm might be statistically significant if lutein is administered at higher doses. Lutein was found to be effective in preventing brain damage after SAH. To our knowledge, this study is the first in the literature to examine the effect of lutein on vasospasm and brain damage after SAH.
