title: [Secondary parkinsonism following midbrain hemorrhage].
abstract: We report a patient who developed right sided cogwheel rigidity and resting tremor after left midbrain hemorrhage. Brain magnetic resonance imaging (MRI) showed left midbrain old hemorrhage including substantia nigra. I-123 iodoamphetamine single photon emission computed tomography (IMP-SPECT) images showed reduced radioisotope (RI)-uptake in the left striatum, thalamus and frontal lobe. Our report shows that focal midbrain lesion can produce parkinsonism.
