Abstract:
Paraneoplastic manifestations are frequently seen in patients with small cell lung carcinoma (SCLC) and can present as diverse clinical entities ranging from endocrinopathies to neurological conditions. Anti-Hu encephalitis is a rare paraneoplastic manifestation most commonly seen in patients with SCLC. This case highlights an SCLC patient who presented with behavioral changes, cognitive deficits, and memory issues, and was found to have anti-Hu encephalitis. The subacute course of this clinical entity should be kept in mind and prompt further investigation in SCLC patients with these symptoms, especially when the laboratory workup of the major culprits is negative or inconclusive.
