Abstract

Paraneoplastic encephalitis presenting with partial clonic seizure is rare. We report a 57-year-old man with clonic seizure in his left arm. He had past medical history of recurrent thymoma and thymomectomy. Magnetic resonance imaging showed multiple brain lesions, but none of them were congruent with the partial seizure. His symptoms and brain lesions resolved after steroid therapy. This is the first reported case extralimbic encephalitis presenting as partial seizure with invasive thymoma in Korea.
