Hemichorea associated with varicella-zoster reinfection and endocarditis. A case report.
A 20-year-old woman developed transient right-sided hemichoreatic movements after household exposure to varicella-zoster. Some days before the appearance of involuntary movements a vesicular rash had occurred. About 6 months later an elevated IgG serum titer against varicella virus was found and two-dimensional echocardiography showed signs of an endocarditis. During the following 2 months the IgG value returned to within the normal range and the choreatic movements disappeared almost totally. The possibility is discussed that endocarditis had been caused and maintained by serum antibodies to varicella-zoster virus which cross-reacted with valvular tissue. Embolization to the region of the left striatum and/or postinfectious encephalitis in this region are assumed to be the most plausible causes of the transient hemichorea.
