    Abstract:
    A 64-year-old right hemiplegic woman, who had been treated for hypertension for 15 years, was admitted to our hospital. Neurologic examination on admission disclosed right hemiplegia and motor aphasia; however, ophthalmoparesis, pupillary abnormality, and blepharoptosis were not evident. Excessive sweating on the right side of the body, which was most marked on the face, was observed. Amount of sweating on the left side of the body was normal. Unilateral hyperhidrosis persisted for more than 2 months. MRI revealed hemorrhagic infarctions in the left basal ganglia, internal capsule, thalamus, hypothalamus, and medial part of the cerebral peduncle. 123I-IMP SPECT disclosed hypoperfusion in the left striatum, thalamus, occipital cortex, and right cerebellar hemisphere. Cerebral angiography revealed arteriosclerotic changes in the basilar artery, but that the left posterior cerebral artery and its branches were not occluded. Unilateral persistent hyperhidrosis is rare after ischemic stroke. Hypothalamic lesion was thought to be responsible for the hyperhidrosis in this patient. As the hypothalamus receives its blood supply from the posterior cerebral artery, unilateral persistent hyperhidrosis may be an important sign of cerebral infarction in the posterior cerebral artery region.
