title: A new neurocutaneous syndrome possibly related to Ota's nevus.
abstract: The case of a 42-year-old Sudanese man is reported who had developed hyperpigmentation of the left face and rapidly progressive right hemiparesis followed by myoclonus at the age of 30. Blue-grey hyperpigmentation was noted in the territory of the left ophthalmic, maxillary and mandibular trigeminal nerve branches, with alopecia of the right face and axilla. CT of the brain revealed left-sided paraventricular calcifications and MRI showed atrophy of the left cerebral hemisphere and mesencephalon, a calcified haemangioma in the left basal ganglia, an old infarct in the right central pons, and cerebellar atrophy. This case resembles Ota's syndrome; however, atypical distribution of the facial nevus, the epidermal location of hyperpigmentation, and the combination of vascular and degenerative cerebral malformations indicate that this is a new hitherto unreported neurocutaneous vascular syndrome.
