Abstract

Reversible cerebral vasoconstriction syndrome (RCVS) is characterized by headaches and multiple transient cerebral vasoconstrictions. Central nervous system (CNS) infections related to the varicella zoster virus (VZV) can complicate various neurological disorders, including cerebral vasculopathy. We present the case of a patient who complained of a severe headache without any other symptoms or focal neurological signs. Brain magnetic resonance angiography showed multiple focal stenoses, especially in the right middle cerebral artery (MCA), and transcranial Doppler sonography revealed increased velocities in the MCA and right anterior cerebral artery. Initially, the headache was attributed to RCVS, and nimodipine infusion was initiated; however, the headache worsened. A cerebrospinal fluid study showed pleocytosis, increased protein levels, and positive polymerase chain reaction markers for VZV. No skin lesions or fever were observed during treatment. Our case emphasizes considering VZV meningitis as a cause of cerebral vasoconstriction, even in the absence of typical signs of CNS infection.
