METHODS: This study is a retrospective observational study conducted in a large tertiary care hospital which was also a Covid center from March 1, 2020 to December 30, 2020.The frequency of neurological manifestations in COVID19 positive patients admitting in the hospital was observed through charts review. All scans were reviewed by two trained neuroradiologists. RESULTS: Total of 2257 patients enrolled through ER with symptoms of COVID and were COVID PCR positive, with initial different severity of chest disease. During their disease a total number of 168 patients underwent cross-sectional imaging of the brain secondary to different neurological symptoms. Negative studies were 108, total positive studies were 60, among which CT was done in 20 patients, MRI was done in 22 patients and 18 patients had both. Predilection to MCA stroke was seen with a frequency of 36.6%, other territorial infarction was of PCA (11.6%), watershed infarctions 11.6% and dual territory infractions (3.3%) CONCLUSION: Out of 2257 patients only 168(7%) underwent neuroimaging. Out of these 168, 108 (64%) were normal. Acute cerebral Infarction was most common finding present in 42(62%) scans.
