Post-infectious neurologic complications in Covid-2019: a complex case report.

A 40-year-old woman with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection developed neurologic manifestations (confusion, agitation, seizures, dyskinesias, and parkinsonism) few weeks after SARS onset. Magnetic resonance imaging (MRI) and cerebrospinal fluid (CSF) analyses were unremarkable, but an 18F-Fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) showed limbic and extra-limbic hypermetabolism. A full recovery, alongside FDG normalization in previously hypermetabolic areas, was observed after intravenous immunoglobulin (IVIg) administration.
