Original abstract
A 62-year-old man complained of resting tremor and posture tremor. In spite of presence of the tremor, other parkinsonian component was very mild. [(11)C]2β-carbomethoxy-3β-(4-fluorophenyl)-tropane ([(11)C]CFT) PET showed asymmetrical reduction of the uptake and [(11)C]raclopride PET showed slightly increased uptake in the striatum. Although he was diagnosed as having benign tremulous parkinsonism (BTP), anti-parkinsonian medications, including anti-cholinergic agent, dopamine agonist and l-dopa, were not effective for his tremor. His tremor gradually deteriorated enough to disturb writing, working, and eating. Because his quality of life (QOL) was disturbed by the troublesome tremor, deep brain stimulation of the subthalamic nucleus (STN-DBS) was performed. After STN-DBS, his tremor was dramatically improved. According to clinical course of our patient as well as previous reports, STN-DBS should be considered as a therapeutic option for BTP patients with severe tremor.
