Department of Neurology, Tri-Service General Hospital, Taipei, Taiwan, ROC.


Parkinsonism secondary to neoplasm is uncommon. We report two patients with bilaterally symmetric parkinsonism as the initial presentation of their brain tumors. The first patient was a 71-year-old woman who presented with a gradual onset of bilateral resting tremor, bradykinesia and rigidity. Computerized tomography (CT) of the brain revealed a large parasagittal tumor in the left frontal lobe. The patient completely recovered from the parkinsonian symptoms after removal of the brain tumor. The second patient, a 74-year-old man with a history of renal cell carcinoma of the right kidney suffered from an insidious onset of bilateral bradykinesia, rigidity and gait difficulty. Cerebral metastasis was noted on the brain CT scan. Early recognition of intracranial tumor as the cause of parkinsonism is important for the management of this type of movement disorder. Moreover, brain CT scanning plays an important role in the differential diagnosis of patients with parkinsonian symptoms.
