Atypical Varicella-Zoster Virus Reactivation: A Case Report

Eur J Case Rep Intern Med. 2023 Aug 11;10(9):003945. doi: 10.12890/2023_003945. eCollection 2023.ABSTRACTVaricella-zoster virus (VZV) commonly causes benign skin manifestations in children; it then establishes a latent infection and may reactivate, causing herpes zoster. The most common zoster complication is postherpetic neuralgia, but complications can also occur without a rash. VZV infection may cause neurological manifestations and even vasculopathy may occur, in both primary and reactivated VZV infection. Thrombotic complications are mainly described in children, while a few case reports have described cerebral venous sinus thrombosis (CVST), deep-vein thrombosis of the lower limbs and pulmonary embolism in adults. In this article we report the case of a young woman who developed systemic thromboembolic sequelae due to a hypercoagulable state following VZV reactivation. She had deep venous lower-limb thrombosis extended to the inferior vena cava (IVC), massive pulmonary embolism and CVST. Moreover, VZV reactivation caused an acute hepatitis and clinical manifestations suggesting viral encephalitis.LEARNING POINTS: Varicella-zoster virus (VZV) commonly causes self-limiting skin manifestation, but even neurological manifestations and thrombotic complications may occur.Only few isolated cases of VZV-related cerebral venous sinus thrombosis (CVST) and other types of deep-vein thrombosis have been reported in adults.Early diagnosis of VZV-related thrombosis and prompt anticoa...
