Febrile headache and leg weakness as the initial symptoms of tickborne encephalitis

Description

A 61-year-old woman presented to the emergency department (ED) with a 1-week fever associated with progressive headache. She also reported weakness and paraesthesias in both legs. In the ED, the patient had normal vital parameters and reported no other medical history. Clinical examination showed a slight neck stiffness; the rest of the examination was normal. Laboratory findings showed a mild inflammatory syndrome. The patient had a lumbar punction; the cerebrospinal fluid (CSF) showed moderate pleocytosis (140 leucocytes/μL with a mononuclear cell dominance). After a normal CT scan, an MRI examination was performed (figures 1and 2). Several days later, intrathecal IgM and IgG antibodies came back positive.
