Palatal and Oromandibular Tremor Secondary to Degenerative Olivary Hypertrophy After Ependymoma Surgery.

Palatal tremor (PT) is a rare movement disorder that involves pharynx, tongue, and other facial muscles. Symptomatic PT is due to lesions on the dentate-rubro-olivary pathways. We present an illustrative case of PT due to degenerative olivary hypertrophy after ependymoma surgery.
