Pontine ischaemic stroke syndromes.

Area of Science:

• Neurology
• Neuroscience
• Clinical Medicine

Background:

• Raymond syndrome is a rare neurological disorder characterized by a specific pattern of cranial nerve and motor deficits.
• It is classified as a 'crossed paralysis,' originating from lesions in the caudal pons.
• Understanding these presentations is crucial for accurate diagnosis and localization of brainstem lesions.

Purpose of the Study:

• To report a case of classic Raymond syndrome.
• To illustrate the clinical presentation and diagnostic considerations for this rare neurological entity.
• To contribute to the literature on brainstem syndromes and crossed paralyses.

Main Methods:

• Case report of a patient presenting with symptoms consistent with Raymond syndrome.
• Clinical examination findings were documented.
• Review of relevant literature on Raymond syndrome and caudal pons lesions.

Main Results:

• The patient, a man in his late 60s, presented with diplopia (double vision), dysarthria (difficulty speaking), and right-sided hemiparesis (weakness on one side of the body).
• These symptoms align with the classic definition of Raymond syndrome: ipsilateral abducens nerve palsy, contralateral facial paresis, and contralateral hemiparesis.
• The presentation localized the neurological deficit to the caudal pons.

Conclusions:

• This case exemplifies a classic presentation of Raymond syndrome, a rare but distinct neurological condition.
• The findings underscore the importance of recognizing crossed paralyses for accurate diagnosis of caudal pons lesions.
• Further case reports are valuable for solidifying the understanding of rare neurological syndromes.
