Objective:
We aim to correlate the prevalence of symptoms of the lateral medullary syndrome (LMS) based on radiological classification.
Methods:
A five-year record of 41 patients diagnosed with LMS and admitted to a tertiary care center in Nepal was reviewed. We used chi-square tests to compare symptoms between rostral and caudal groups and different horizontal subtypes.
Results:
The subtype prevalence in the horizontal classification of LMS was large (31.7%), lateral (22%), dorsal (19.5%), typical (14.6%), and ventral (12.2%). The most common symptoms in the typical subtype of the horizontal classification were: pain/temperature loss in the contralateral body (7.3%) and dysphagia (7.3%); in the ventral subtype, swaying on the Romberg test (12.2%), dysarthria (9.8%) and dizziness (9.8%); in the dorsal subtype, headache (12.2%) and vomiting (12.2%). Whereas headache (22.2%) and lateropulsion on standing (14.6%), swaying on the Romberg test (14.6%), nausea/vomiting (14.6%) were common in the large subtype, and nausea/vomiting (19.5%) and headache (17.1%) in the lateral subtypes. Whereas, in rostrocaudal classification, the rostral subtype (61%) was more common than the caudal subtype (31%). There was no significant variation in symptoms based on the rostrocaudal classification of LMS.
Conclusion:
The common clinical manifestations are different for different radiological subtypes of LMS. Further comprehensive studies are essential to understand the prevalence of symptoms in different radiological subtypes and the clinical-radiologic correlation in LMS.
