Non-aneurysmal Perimesencephalic Subarachnoid Hemorrhage in A COVID-۱۹ Patient: Case Report and Review on Subarachnoid Hemorrhage Patterns in COVID-۱۹

Background and Importance: The novel SARS-CoV-۲ virus has had an undeniable effect worldwide in different aspects. Although cerebrovascular diseases, especially subarachnoid hemorrhage (SAH), have already been reported in COVID-۱۹ patients, little is known about various types and patterns of SAH in these patients. Case Presentation: A ۶۳-year-old woman was admitted to the emergency department with a headache. Her headache was severe (Hunt and Hess score, grade ۲). She was diagnosed with COVID-۱۹ 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-۱۹, the perimesencephalic hemorrhage in our case is a novel type. Although not uncommon among non-infected populations, SAH occurrence in COVID-۱۹ patients has not been reported before and needs further investigation.
