METHODS
Patient with history of peripheral paresis of right facial nerve, 1 month after symptoms appearance and treatment, developed fever, vomiting, grand mal seizure, decreased level of consciousness, confusion, hallucinations and agitation. The patient initially presented a clinical picture of viral LE. which confirmed by CSF. MRI brain showed areas with pathological intensity signal in the region of limbic system unilateral. During the clinical evaluation a renal carcinoma was discovered and a nephrectomy has been performed.
