Introduction:

Foville syndrome (inferior medial pontine syndrome) is a clinical entity that makes part of a subclassification of a broader category of posterior circulation stroke. It is characterized by a blockage of the basilar artery caused by lesions in the pontine tegmentum. This syndrome has a very low incidence worldwide, but its clinical relevance is considerable.

Case report:

A 41-year-old patient without any medical history was admitted to the emergency department due to signs of focal neurologic deficits. Imaging findings were compatible with an ischemic lesion in the brainstem, and cerebral angiography showed involvement of the basilar artery territory. The patient was diagnosed and followed up in the intensive care unit (ICU) until his recovery.

Conclusion:

Foville syndrome is a rare disease with high morbidity and mortality. Early recognition and a multidisciplinary approach are decisive to improve the patient's prognosis.
