Relapsing-remitting multiple sclerosis in a patient with Huntington's disease

A woman in her 50s with confirmed Huntington's disease developed right-sided sensory symptoms and was diagnosed with relapsing-remitting MS based on MRI findings of demyelinating lesions, oligoclonal bands in cerebrospinal fluid, and McDonald diagnostic criteria. The case underscores the importance of evaluating new neurological symptoms in patients with neurodegenerative conditions rather than attributing all manifestations to a single disease process.
