Yang Tang MD, PhD, Abstract Co-Author: Nothing to Disclose

This pictorial essay presents an approach to the differential diagnosis of spinal cord lesions identified on MR imaging. We will discuss differential causes for intramedullary cord abnormalities. Topics that will be covered in the following essay include vascular supply of the spinal cord and consequences of arterial and venous compromise, vascular malformations and vascular tumors. 

This pictorial essay presents an approach to the differential diagnosis of spinal cord lesions identified on MR imaging.  The purpose of this exhibit is:To review the anatomy and pathophysiology of spinal cord arterial and venous blood supply.To discuss various etiologies of cord pathology and imaging features. Table of Contents/Outline: Anatomy and pathophysiology of cord vasculature Spinal Cord Infarction- Arteriovenous Fistula (AVF)- Arteriovenous Malformation- Discuss pathology, etiology, imaging features and example MRI cases of each. Vascular tumors- Discuss pathology, etiology, imaging features and example MRI cases for each: Hemangioblastoma, Astrocytoma, Ependymomas, and Metastatic Renal Cell Carcinoma. The major teaching points of this exhibit are: Review of vascular anatomy and how it relates to cord pathology. Key imaging features of non-traumatic spinal cord pathology. Common imaging pitfalls.
