A 36-year-old woman with a history of hypopituitarism presented with a headache on the first day. Gradually, diplopia, ataxia, dysarthria, dysphagia, hypoesthesia, limb weakness, hypersomnolence, and respiratory muscle paralysis were developed in less than ten days. Based on brain computed tomography scan, magnetic resonance imaging scan, nerve conduction studies, cerebrospinal fluids analysis, anti-ganglioside antibodies and hormones tests, and clinical investigations, we diagnosed the patient with BBE overlapped with GBS. Treatment with corticosteroids and immunoglobulin resulted in clinical improvement. To our knowledge, this is the first case report of a hypopituitarism patient with BBE overlapped by GBS in English literature. Hypopituitarism patients have immune dysfunction. Based on previously reported autoimmune diseases associated with triggering GBS and its subtypes, hypopituitarism could be considered a noninfectious trigger.<\/jats:p>","DOI":"10.4103\/0028-3886.329589","type":"journal-article","created":{"date-parts":[[2024,9,7]],"date-time":"2024-09-07T15:07:56Z","timestamp":1725721676000},"page":"1397-1399","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":4,"title":["A
