Objective:

Describe unusual etiology of movement disorders (MD).

Background:

Benign brain tumor can be manifested by MD. The clinical description and role of brain imaging in the diagnosis of a patient with MD symptoms is discussed.

Methods:

We collected patients during the external consultation of neurology which presented MD with or no other neurological symptoms; having an imaging suggestive of a brain tumor.

Results:

Five patients (3 men, 2 women) with a mean age of 38.2 ± 4.2 years consulted with MD, among them 2 had partial seizures. The rest of neurological examination including cognitive functioning was unremarkable. The patient’s family history was negative for any neurological conditions, including Huntington’s disease, chorea and other MD. Imaging by computed tomography or magnetic resonance imaging was mandatory asked in the diagnosis of neurological disorders. All of these tumors were extrinsic with reference to basal ganglia and thalamus: there were four meningioma with parkinsonism and one neurofibromatosis with focal dystonia. We observed a relief of MD after the surgery in all of patients.

Conclusions:

Movement disorders in general are uncommon presenting features of brain tumors. The mechanical pressure caused by the enlargement could lead to various movement disorders, which may even coexist as presented in our case. Early recognition of such lesions by imaging is important to arrest further deficit.
