MR Imaging of Autoimmune Inflammatory and Demyelinating Myelopathies

This article examines the MR imaging features of the most common autoimmune inflammatory and demyelinating myelopathies, which encompass disorders characterized by inflammation and subsequent damage to the myelin sheath within the spinal cord. The diagnosis of these conditions relies on a comprehensive approach that includes clinical assessment, neuroradiological evaluation, and laboratory investigations. MR imaging is essential in identifying key features such as signal change, lesion dimension, gadolinium enhancement pattern, and temporal evolution, overall helping to narrow down the differential diagnosis in patients with myelopathy.
