Meningoencephalitis or meningitis in relapsing polychondritis: four case reports and a literature review.

摘要

Relapsing polychondritis (RP) is a rare autoimmune disease that affects cartilage throughout the body, causing episodic and progressive inflammation. Although rare, RP has diverse acute and subacute nervous system complications, which may sometimes precede systemic manifestations. Here, we report four patients with RP who presented with meningoencephalitis or meningitis without infectious aetiology. In addition, we review the literature for this disease with regard to clinical manifestations and treatment options.
