Abstract
Tick borne encephalitis (TBE) is an important viral encephalitis in central and eastern Europe. Cerebrospinal fluid (CSF) pleocytosis has been described in all published patients so far. This may be due to selection bias, however, as CSF pleocytosis is often used as a case definition parameter. The frequency of TBE without CSF pleocytosis is unknown. We report two cases who developed severe TBE ...
Abstract
Tick borne encephalitis (TBE) is an important viral encephalitis in central and eastern Europe. Cerebrospinal fluid (CSF) pleocytosis has been described in all published patients so far. This may be due to selection bias, however, as CSF pleocytosis is often used as a case definition parameter. The frequency of TBE without CSF pleocytosis is unknown. We report two cases who developed severe TBE without CSF pleocytosis. A normal CSF cell count should therefore not discourage from the differential diagnosis of TBE and deter from serological testing in patients with a clinical constellation suggesting TBE.
