[Late symptomatic initiation of unilateral cerebellar hypoplasia].
A 65-year-old woman developed a progressive action tremor on her left hand for the last two years. On examination an intentional left hand tremor with dysmetria and tendency to deviate to left on tandem were identified. There was no mental deterioration. CT scan and MR imaging disclosed a marked unilateral, left, cerebellar hypoplasia. MR also showed multiple lacunae. Neurological family disease and exposition to drugs or alcohol were not present. In some cases cerebellar hypoplasia could become symptomatic at advanced age as result of concurrent cerebral disease affecting the compensating structures for congenital defect. In this patient a vascular mechanism is suggested as possible late trigger.
