[Following sensory neuropathy, anti-Hu antibody-positive paraneoplastic neurological syndrome presenting with limbic encephalitis occurs after complete remission].

Paraneoplastic limbic encephalitis is a rare neurological disorder that frequently precedes the detection of malignancy. We report the case of a 68-year-old male with small-cell lung cancer who developed paraneoplastic limbic encephalitis associated with presence of the anti-Hu antibody, after achieving complete remission of the tumor by chemotherapy. The patient visited our hospital because of progressive sensory disturbance of the distal extremities at 65 years of age.
