[Parkinson disease associated to a brain tumor: a case report].
We are presenting an uncommon case of cerebral tumor whose major manifestation was parkinsonism. The patient was a 50-year-old woman presented with a 5-month history of tremor of the right hand, particularly at rest, and headache. On neurological examination of March, 1987 there were: slight right-sided hemiparesis with symmetrical hyperreflexia; discrete bradykinesia in combination with cogwheel rigidity also on the right-side; resting tremor of the right hand; and bilateral papilledema. The neuropsychological examination disclosed: nominative aphasia, impaired recent memory and right-left disorientation. The computed tomography showed a large, left frontotemporal tumor. Angiograms of the left internal and external carotid arteries revealed a tumor blush in the left frontotemporal region supplied by a enlarged middle meningeal artery. An electromyogram revealed a 4-6 HZ tremor on right hand. A course of treatment with dexamethasone 16 mg/day and levodopa plus benzerazine (500 mg/day) was unsuccessful. A left fronto-temporo-parietal craniotomy was performed and an attached sphenoid wing tumor was macroscopically completely removed. Microscopy indicated that the tumor was a meningioma. Postoperatively, the patient made an uneventful recovery. After two weeks, her right-sided palsy and parkinsonism had disappeared, and neuropsychological deficits improved. Two months later there was no abnormalities on neurological and neuropsychological examination. It was concluded that the parkinsonism was caused by mechanical pressure on the basal ganglia.
