Paraneoplastic neurological syndromes (PNS) are a rare and heterogeneous group of immune-mediated neurological disorders. We report the case of a 32-year-old woman with progressive and severely disabling neurological symptoms. After excluding alternative causes, she was diagnosed with an atypical pulmonary carcinoid tumor. Surgical resection led to partial clinical improvement. This case underscores the importance of considering PNS in patients with unexplained neurological symptoms and highlights the need to investigate for underlying neoplasms as a potential trigger.
