Presentamos un caso de meningioma de la hoz cerebral asociado a himiparkinsonismo contralateral con déficit de perfusión en ganglios de la base demostrado mediante tomografía computarizada por emisión de fotones (single-photon emission computed tomography o SPECT) cerebral. La exéresis del tumor condujo a la remisión completa de la sintomatología así como a una importante mejoría en la perfusión de las zonas afectadas. Se citan diferentes procesos intracraneales asociados a síndrome parkinsoniano y se discuten los mecanismos fisiopatológicos propuestos según su localización anatómica.
We report the case of a meningioma of the falx associated with contralateral hemiparkinsonism and reduced uptake in brain single-photon emission computed tomography (SPECT). Complete removal of the tumor led to total remission of extrapyramidal symptoms and improved perfusion of the previously affected areas. We review the subject of parkinsonism associated with intracranial mass lesions and discuss the different causative mechanisms.
