title: Acute hemiplegia with lacunar infarct after varicella infection in childhood.
abstract: We report 4 cases of acute hemiplegia and a small low-density lesion on computerized tomography (CT) after varicella infection. In 3 of them, CT in the acute hemiplegic stage, and later, reveals the development of lacunar infarct around the internal capsule. Focal low density may be caused by occlusive vascular lesions of the penetrating arteries. Varicella infection may play an important role as one of the causes of acute hemiplegia in childhood producing lacunar infarct, as well as delayed hemiplegia, reported previously in herpes zoster ophthalmicus.
