A rare case of undulatory rhythmic lingual myoclonus in a patient with intracranial hemorrhage and diffuse pontine lesion

We describe a 35-year-old man, who suffered a severe intraventricular hemorrhage and was admitted to the intensive care unit of our tertiary clinic. Two weeks after the incident, while in ICU, a neurological examination revealed persistent, undulating, rhythmic, myoclonic tongue movements. The diagnostic evaluation via CT scan, MRI and EEGs elicited a diffuse brainstem lesion as well as multiple corpus callosum lesions as a considerable underlying etiology. This case presentation attempts to update the current investigation of the rare phenomenon of lingual myoclonus.
