BACKGROUND: Brain tumors are uncommon etiologies of parkinsonism. The clinical manifestations of tumoral parkinsonism may sometimes resemble those of idiopathic origin. Increased awareness of this rare entity is important for an earlier prompt diagnosis and treatment.
REVIEW SUMMARY: A previously healthy, 60-year-old man developed slowly progressive right-sided resting tremor and bradykinesia over 8 months. Although idiopathic Parkinson disease was the initial diagnosis, the parkinsonian symptoms were not responsive to medical treatment with levodopa and a dopamine agonist. Brain computed tomography failed to reveal an intracranial lesion. Brain magnetic resonance imaging demonstrated an infiltrative, slightly enhancing mass in the left mesial temporal lobe extending to the left basal ganglion and insula. Histopathologic findings confirmed the diagnosis of high-grade astrocytoma. The parkinsonian symptoms subsided after tumor removal; however, ipsilateral hemiparesis developed postoperatively.
CONCLUSIONS: Neuroimaging is recommended for investigation of atypical parkinsonism. We suggest that brain magnetic resonance imaging is preferred for patients with drug-resistant parkinsonism or concurrent signs apart from extrapyramidal symptoms, because some mass lesions are not observed by computed tomography scan.
