A Rare Adolescent Presentation of Morvan Syndrome: Diagnostic Challenges and Therapeutic Response

Year: 2026

Type: article

Abstract: Morvan syndrome is a rare autoimmune disorder that predominantly affects adults, but it can also present in adolescents with atypical symptoms. This case of a 17-year-old patient exhibited severe back pain, muscle twitching, visual hallucinations, and hyponatremia, without the thymoma or malignancy commonly observed in adult cases. Early diagnosis and prompt immunotherapy with corticosteroids and plasmapheresis resulted in significant symptom improvement, highlighting the importance of timely intervention in complex neuroimmunological disorders.
