Brain Tumor Presenting with Parkinsonism.

Movement disorders caused by brain tumors are rare. The diagnosis of idiopathic Parkinson's disease (PD) is based foremost on clinical findings. However, not performing imaging already within the initial diagnostic workup in patients presenting with symptoms of PD can delay or miss a serious diagnosis and consequently proper treatment. We describe and discuss a 59-year-old female patient who presented for several months of increasing tremor in her left hand, which was caused by a large meningioma located in the right frontal area, pressing on the right frontal lobe and nucleus lenticularis.
