Abstract
Objectıve: Brain tumors are rare causes of parkinsonism. The tumors causing neoplastic parkinsonism are astrocytomas,
meningiomas, craniopharyngiomas, colloid cysts and more rarely, metastatic brain tumors. Mass effect to basal ganglia takes
an essential role in the mechanism of pathological findings.
Materıals & Methods: We present an unusual case of parkinsonism secondary to a metastatic brain tumor. A 60 year old male
patient was admitted to our hospital with a history of gradually decreasing speech content, slowing of speaking, blurring of gaze
and slowing of movements for two months. The neurological examination had mask face, hypophonic speech, bradykinesia
and rigidity in the left arm and leg. Idiopathic Parkinson’s disease (IPD) was first suspected during diagnosis, but the presence
of small cell lung cancer in patient past history and a rapid progression in neurological seymptoms suggested the possibility of
secondary parkinsonism and brian magnetic resonans imaging (MRI) was performed immediately.
Results: A 27×30 mm sized lesion with very distinct edema effect and heterogeneous contrast enhancement in the right
frontoparietal area was found in MRI. The lesion was initially interpreted as a metastatic brain tumor, the patient underwent
surgery and all extrapyramidal findings were resolved.
Conclusion: Uncommon causes of parkinsonism like brain tumors may resemble clinical features of IPH; thus, we wanted
to emphasize that imaging should once again be performed for differential and accurate diagnosis and treatment planning,
espacially in cases with rapid and progressive course.
