Gasperini Syndrome: A Case Report and Systematic Review and Proposing a New Definition.

Gasperini syndrome (GS), a rare brainstem syndrome, is featured by ipsilateral cranial nerves (CN) V-VIII dysfunction with contralateral hemibody hypoesthesia. While there have been 18 reported cases, the GS definition remains ambiguous. We report a new case and reviewed the clinical features of this syndrome from all published reports to propose a new definition.
