Clinical and radiological aspects of Villaretʹs syndrome

A 68-year-old man with a history of large cell lung carcinoma presented 1 year after surgical management of the initial lesion, with a complete unilateral IX-XII cranial nerve palsy with Hornerʹs sign. This rare multiple cranial nerve palsy is called Villaretʹs syndrome. It suggests an extracranial lesion located in the retroparotid space. Complete basal skull radiology work up including computed tomography and magnetic resonance imaging confirmed the location of the causal lesion in the retroparotid space.
