Holmes’ tremor (rubral tremor, cerebellar outflow tremor) is characterized by rest, intention and postural tremor, often localized to one upper extremity, associated with ipsilateral dysmetria and dysdiadochokinesia. We describe a case of successful treatment of Holmes’ tremor with unilateral nucleus ventralis intermedius (VIM) thalamotomy. The subject is a 43-year-old woman with unremarkable previous medical history. She presented with complete left hemiparesis in the context of human immunodeficiency syndrome and the magnetic resonance image disclosed a contrast-enhancing lesion in right brain peduncle, in topography of red nucleus. She developed a progressive rest, intention and postural tremor in left upper limb. She was submitted to a stereotactic biopsy and the tremor became worse. She performed awake right VIM thalamotomy, with immediate complete resolution of tremor. There were no complications after procedure, and the result is stable after six months. We highlight the role of thalamotomy in cases like ours, once patient recovered well and, due to HIV, will need further neuroimage studies to evaluate neurologic complications of HIV. Deep brain stimulation in such cases may interfere with coming neuroimage quality and may act like a foreign body.
