Various neurological symptoms have been reported as the side effect of COVID-19 vaccines. Vaccine-associated acute Cerebellitis is very uncommon. Here, we report a 45-year-old female with acute onset cerebellitis, beginning 10 days after administration of Sinopharm vaccine. Her CSF COVID-19 PCR was found to be positive, with no pulmonary symptoms.

sputum acid-fast bacilli were positive and anti-TB treatment was started. Her cerebrospinal fluid results were normal except for a positive nested polymerase chain reaction (PCR) for tuberculous. She responded to protocol for treatment of status epilepticus and anti-TBM treatment and her level of consciousness improved and she became fully aware

We hypothesize that the hypercoagulable state related to COVID-19 exacerbated the underlying hereditary thrombophilia due to MTHFR-gene mutation.
