摘要

Varicella zoster virus (VZV) vasculopathy is a rare but severe neurological complication that frequently results in a reversible cerebral vasoconstriction syndrome (RCVS). Diagnosis is often delayed because early manifestations are nonspecific and radiologic findings often overlap with those of other cerebrovascular disorders. We describe the fatal case of a heavily pretreated 60-year-old man with refractory diffuse large B-cell lymphoma undergoing evaluation for chimeric antigen receptor (CAR) T-cell therapy. The patient developed multifocal intracranial arterial stenosis and an acute infarction during chemotherapy-induced immunosuppression. The initial radiological features suggested RCVS; however, cerebrospinal fluid (CSF) analysis using polymerase chain reaction (PCR) and anti-IgG antibodies confirmed the presence of VZV. Despite intravenous acyclovir and high-dose corticosteroids, the vasculopathy progressed rapidly, resulting in recurrent infarctions, seizures, and death. This case highlights the diagnostic complexity of VZV vasculopathy in immunocompromised patients and underscores the importance of early CSF evaluation, heightened clinical vigilance for opportunistic viral complications, and the potential diagnostic value of vessel wall magnetic resonance imaging (MRI) in differentiating VZV vasculopathy from mimicking conditions such as RCVS.
