Answer

Case reports describe patients who meet the diagnostic criteria for both Takayasu arteritis and giant cell (temporal) arteritis, although subtle differences exist in the distribution of arterial involvement in the two diseases. [30, 31] Some authors have advanced the notion that the two disorders may represent a spectrum of a single disease, with the manifestations influenced by hormonal, immunologic and vascular factors. [31] Virological and pathological findings and response to antiviral treatment in one patient support a possible etiologic role for varicella-zoster virus (VZV). [30]
