ABSTRACT We
report a case of COVID-19-associated
meningoencephalitis with a
fatal outcome in a
male patient with concomitant influenza A,
who had been hospitalized at the beginning of 2022, in the Northeastern region of
Brazil. He died due to
cardiopulmonary arrest after developing
status epilepticus on the third day of
hospitalization. The
SARS-CoV-2 RNA was detected in
cerebrospinal fluid and Influenza A was detected in the nasopharyngeal swab.
Meningoencephalitis due to COVID-19 is a rare manifestation and
physicians must be aware of this complication, mainly during the
pandemic. In viral co-circulation situations, the possibility of respiratory
coinfections should be remembered.
