Spinal Cord Involvement in Neurosarcoidosis: A Case of Longitudinally Extensive Transverse Myelitis at Disease Onset

Acute‐onset neurological deficits in otherwise healthy individuals warrant a broad differential diagnosis. Neurosarcoidosis presenting as longitudinally extensive transverse myelitis is rare, mimicking demyelinating, infectious, or neoplastic disorders. Early recognition, histopathological confirmation, and timely immunosuppressive therapy are crucial. Further research is mandatory in optimizing treatment regimens, especially for refractory neurosarcoidosis cases.
