Abstract:
Parkinsonism is characterized by clinical symptoms of rigidity, bradykinesia, tremor, and gait disturbance. There are many causes of secondary parkinsonism. The present report discusses a secondary parkinsonism of extrapontine myelinolysis (EPM) without central pontine myelinolysis (CPM) after rapid correction of hyponatremia. EPM is a demyelinating process of the brain. EPM with CPM is relatively common, but EMP without CPM is rare. A 57- year-old woman with Tsutsugamushi disease had a subacuteonset of parkinsonism on the fourteenth day after a rapid correction of severe hyponatremia. Magnetic resonance imaging of the bilateral basal ganglia showed a high signal intensity on T2-weighted images, and a low signal on T1- weighted images. She was started on levodopa, and parkinsonian features slowly improved. We report an unusual case of EPM without CPM, that presented with parkinsonism.
