Role of MRI in Evaluation of Patients Clinically Diagnosed Non-Traumatic Myelopathy
Main Article Content
Abstract
Introduction: Any neurological deficiency arising from injury or malfunction of the spinal cord, whether it be sensory, motor, or autonomic, is referred to as myelopathy. Myelopathy can be caused by a wide range of illnesses. These diseases can have a variety of etiologies, including infections, inflammatory, neoplastic, vascular, degenerative, or deficient disorders.
Aims: MRI characterization of spinal cord lesion and correlated them with clinical findings. To classify compressive and non-compressive nature of the lesion based on MRI.
Materials and method: The present study involved 50 patients having non traumatic, in the Department of Radiodiagnosis and Imaging, of BMCH over a period from October 2020 to December 2021.
Result: In this study of 19 cases of non-compressive myelopathy are found. Etiology of these cases were Acute transverse myelitis (post-infective) (47.5 %), Multiple sclerosis (15.8%), Neuromyelitis spectrum disorders (10.5%), Subacute combined degeneration (15.8%), Spinal infarct (5.2%) and post radiation myelitis (5.2%).
Conclusion: We find that the most prevalent cause of compressive myelopathy is spinal TB, while the most common cause of non-compressive myelitis is post-infective acute-transverse myelitis. The amount of spinal cord involvement and the compartments (Extradural, Extramedullary-Intradural, and Intramedullary) of compressive causes of myelopathy are effective means of characterizing them. The degree of spinal cord involvement and short segment or long segment involvement are characteristics of non-compressive causes of myelopathy.
