Relapsing polychondritis (RP) is an episodic and progressive inflammatory disease of cartilaginous structures. Its diagnosis is based primarily on clinical features such as laboratory parameters, biopsy. Neurological complications occur in 3% of the cases and are classified as an important cause of death. The cranial nerve disorders are most common but hemiplegia, ataxia, myelitis, polyneuritis, seizures, confusion, hallucination and headache can also happen. The aetiology of central nervous system involvement is still unknown. Moreover stroke has rarely reported in these patients. The diagnosis of stroke is challenging because of its rarity among these patients. Perhaps vasculitis is the common underlying mechanism. Also meningitis and encephalitis can occur during the course of RP. A 44 year-old woman was admitted with uncontemplated left hemiparesis, redness, swelling, and tenderness of the metacarpophalangeal and interphalangeal joints of the right hand and the cartilaginous portion. White blood cell count, C-reactive protein and the erythrocyte sedimentation rate were elevated. Vasculitis biomarkers were normal in our patient. Carotid and vertebral artery doppler ultrasonography, cranial and cervical MR Angiography were normal. Echocardiography showed a mild mitral valve prolapse and regurgitation. Our patient had the history of auricular polychondritis but she had not been diagnosed. Hemiparesis was her first neurological manifestation that led her to doctors for diagnosis. Our patient fulfilled the criteria of RP so no biopsy was needed. She was treated with oral prednisolone (80 mg/day) and aspirin (300 mg/day) and now she is on 10 mg prednisolone and 150 mg azathioprine. Two months later her physical and neurological symptoms returned to normal.

Relapsing polychondritis (RP) is a rare autoimmune disorder affecting cartilage. Limbic encephalitis is a rare central nervous system manifestation of RP. This current case report describes a 66-year-old Chinese male patient who complained of developing myoclonus in the left leg, ataxia and speech difficulties 3 weeks prior to hospital admission. The patient presented with cognitive impairment, sleep disorder and extrapyramidal symptoms. The patient was diagnosed with RP that affected auricular cartilage, which also manifested as limbic encephalitis. Magnetic resonance imaging showed bilateral temporal lobe lesions involving the hippocampi and basal ganglia. Signal abnormalities in the white matter persisted during the 15-month follow-up period after treatment with corticosteroids and intravenous immunoglobulin. Over the same period, the bilateral hippocampi showed significant atrophy.
