Although cerebrovascular diseases, especially subarachnoid hemorrhage (SAH), have already been reported in COVID-19 patients, little is known about various types and patterns of SAH in these patients. Case Presentation: A 63-year-old woman was admitted to the emergency department with a headache. Her headache was severe (Hunt and Hess score, grade 2). She was diagnosed with COVID-19 by a positive nasopharyngeal swab PCR test. Her CT scan revealed a perimesencephalic hemorrhage, thick SAH without any signs of hydrocephalus or intraventricular hemorrhage. Conclusion: Regarding the different associations of SAH with COVID-19, the perimesencephalic hemorrhage in our case is a novel type. Although not uncommon among non-infected populations, SAH occurrence in COVID-19 patients has not been reported before and needs further investigation. M3 10.32598/irjns.7.4.7 ER -
