Abstract
Anti-Hu antibody-related paraneoplastic neurologic syndrome (PNS), a rare disease primarily associated with small cell lung carcinoma, is characterized by diverse neurologic manifestations. Central sleep apnea, although rare, is specific to anti-Hu antibody-related PNS. Herein, we present a case of out-of-hospital cardiac arrest attributed to hypercapnic central sleep apnea and detail the subsequent workup that revealed anti-Hu brainstem encephalitis. A malignancy survey revealed mediastinal small cell carcinoma. The patient was treated by tumour excision, chemotherapy, plasma exchange, and high-dose glucocorticoids. Though the neurologic damage caused by anti-Hu antibody was documented to be relatively irreversible in literatures, such hypercapnic central sleep apnea resolved in our case about 1 month later.
期刊介绍：
Respirology Case Reports is an open-access online journal dedicated to the publication of original clinical case reports, case series, clinical images and clinical videos in all fields of respiratory medicine. The Journal encourages the international exchange between clinicians and researchers of experiences in diagnosing and treating uncommon diseases or diseases with unusual presentations. All manuscripts are peer-reviewed through a streamlined process that aims at providing a rapid turnaround time from submission to publication.
