[Ataxic hemiparesis and simultaneous supra- and subtentorial hematomas].

In a chronically hypertensive woman with a rapidly developing right ataxic hemiparesis syndrome, computed tomography and magnetic resonance imaging (MRI) revealed two small unrelated hemorrhages: one in the posterior limb of the left internal capsule, the other in the right cerebellar hemisphere. In this patient, the ataxic hemiparesis syndrome might have resulted either from the association of the two lesions or from the capsular hemorrhage alone. The rarity of simultaneous hypertensive hematomas and the value of MRI in the diagnosis are underlined.
