Abstract

We present a case of hemiballismus related to cryptococcal meningitis. A 23 year-old man was hospitalized because of involuntary movements of his left side, confusion, hyperpyrexia, neck stiffness, bilateral papilledema, right hemiparesis and bilateral pyramidal signs. Diagnosis was made by CSF examination demonstrating cryptococci by india ink. CT with contrast showed hyperdense lesions in the head of the right caudate nucleus, in the left internal capsule and in the frontal and occipital lobes. After treatment with amphotericin B, 5-fluorocytosine and haloperidol, he experienced rapid recovery with disappearance of hemiballismus. To our knowledge, this is the first report of hemiballismus caused by cryptococcal meningitis.
