Seizures in anti-Hu-associated extra-limbic encephalitis: Characterization of a unique disease manifestation.

ABSTRACT: Anti-Hu-associated neurologic autoimmunity most often occurs in the context of small cell lung cancer and typically presents with peripheral neuropathy, cerebellar ataxia, and/or limbic encephalitis. Extra-limbic encephalitis causing seizures is a rare disease manifestation, with only sparse reports in the literature. Herein we present a patient with seizures in anti-Hu-associated extra-limbic encephalitis, and review the literature for other cases to more fully characterize this entity. Among 27 patients we identified, the median age was 46 years (range: 2-69 years) and 18 of 27 (67%) were female. Focal motor seizures were most common, followed by ictal expressive speech difficulty. Seizure semiologies along with neuroimaging findings most frequently suggested the involvement of the peri-
