Midbrain Tremor

✓ This 49-year-old man gradually developed a disabling action tremor in the proximal right upper extremity 8 months after suffering a pontine tegmental hemorrhage. The intraoperative microrecording in the nucleus ventralis intermedius (VIM) of the left thalamus revealed tremor-synchronous grouped discharges with a vigorous (2.7 Hz) action tremor predominantly in the shoulder and upper arm. High frequency electrical stimulation in the VIM did not affect the tremor. A posteroventral pallidotomy (PVP) was performed and resulted in the successful alleviation of all tremor activity. Posteroventral pallidotomy is known to alleviate parkinsonian tremors, especially those occurring in the contralateral lower extremity, trunk, and proximal segment of the contralateral upper extremity. The authors consider the pallidoreticular pathway to be an important tremor-mediating pathway for the proximal segment of the upper extremities and believe it can be controlled more effectively by PVP than by VIM thalamotomy, as demonstrated by the PVP-induced resolution of the midbrain tremor observed in this case.

Uncommon Condition

We report four cases of hypertrophic olivary degeneration (HOD) , the first three cases after pontine hemorrhage from cavernous malformation, arteriovenous malformation (AVM) and hypertension and the latter one after surgery for removal of Non-Hodgkin lymphoma (NHL) involving dentate nucleus. The magnetic resonance (MR) features of all cases and diffuse tensor imaging (DTI) with fiber tractography findings in one case are described as well as discussion and review literature of this uncommon condition are performed.
