Approach To Diagnosis Of Intramedullary Spinal Pathologies 2014

Category General Spine Manish Bajaj Tushar Chandra, M.D. Dhiraj Baruah, MD Toshio Moritani Purpose Intramedullary Spinal Pathologies may result from a diversity of etiologies including developmental,traumatic, inflammatory/infective,demyelinating, degenerative, vascular and neoplastic causes. The purpose of this exhibit is to describe relevant anatomy important for imaging interpretation and establish a clinicoradiological approach to reach final diagnosis. Materials & Methods An overview of normal anatomy of spine with compartmental classification will initially be provided with diagrammatic representation of cross sectional anatomy of cord and its blood supply.A step-by-step approach to diagnosis of intramedullary pathologies will be suggested to reach final diagnosis. Results This educational exhibit will guide the development of an easy systematic approach to diagnosis of common intramedullary spinal pathologies and narrow the differential diagnosis. Conclusion An understanding of the normal anatomy of spinal cord and characterstic imaging findings of intramedullary spinal pathologies is important for making a diagnosis References 1.Radiologic-pathologic correlation of pediatric and adolescent spinal neoplasms: Part 1, Intramedullary spinal neoplasms.Smith AB et al.AJR Am J Roentgenol. 2012 Jan;198(1):34-43 2.Magnetic resonance imaging of intramedullary spinal cord lesions: a pictorial review.Do-Dai DD et al.Curr Probl Diagn Radiol. 2010 Jul-Aug;39(4):160-85
