Abstract
The spinal cord is a complex and densely packed structure of nerve tissue, and magnetic resonance imaging (MRI) is an excellent imaging modality for evaluating its pathologies. Among the distinct functional zones of the spinal cord, the dorsal (or posterior) column is a crucial white matter region responsible for transmitting sensory information and is located in the posterior aspect of the spinal cord. Myelopathies of the dorsal column typically appear as high signal intensity in this region on T2-weighted images. They may arise from several pathological processes, including degenerative, metabolic, inflammatory, infectious, and traumatic conditions. Identifying the specific etiology through characteristic MRI features, along with the patient’s clinical presentation, is crucial for developing an effective treatment plan and understanding the prognosis of sensory abnormalities. This study reviews myelopathies that specifically affect the dorsal column and outlines the MRI findings that aid in the differential diagnosis of these dorsal column lesions.
