Paraneoplastic limbic encephalitis (PLE) is a rare neurologic disorder that can be combined with several systemic tumor. PLE is commonly associated with small cell lung carcinoma, but others are uncommon. The cause is unknown, but it is thought to be a autoimmune disorder developing secondary to carcinomatous process. Progressive neurologic symptoms usually predate the diagnosis of cancer, most symptoms usually improve after resection of tumor. PLE can combined with several tumors, but it is very rare with immature ovarian teratoma. We report a case of 31-year-old woman with PLE combined with an immature ovarian teratoma whose neurologic symptoms improved after resection of primary tumor.
