Cheiro-oral syndrome (COS), a sensory disturbance affecting the hand and mouth, can result from brainstem lesions, not just parietal or thalamic ones. Further neurological investigation is recommended for suspected COS cases, particularly without a migraine history.

Area of Science:

Neurology
Neuroscience
Sensory Systems

Background:

Cheiro-oral syndrome (COS) is characterized by unilateral sensory disturbances affecting the hand/fingers and corner of the mouth.
Historically, COS has been linked to lesions in the parietal lobe or thalamus.

Observation:

This study describes six patients presenting with typical cheiro-oral syndrome.
In five of these patients, well-circumscribed brain lesions were identified at various locations.

Findings:

Lesions causing COS can occur at the brainstem level, challenging previous assumptions.
The precise pathogenetic mechanisms underlying this sensory symptom complex remain under investigation.

Implications:

The findings suggest that brainstem lesions should be considered in the differential diagnosis of COS.

A comprehensive neurological workup is crucial for diagnosing COS, especially in patients without a history of migraine.

Further research is needed to fully elucidate the pathophysiology of cheiro-oral syndrome.
