The purpose of this exhibit is: Understand longitudinal extensive transverse myelitis (LETM) definition, how it differentiates from acute partial transverse myelitis and acute complete transverse myelitis. Review the differential diagnosis of extensive T2 signal in the spinal cord, highlighting the classic signs and MRI findings. Utilize a pattern based approach to narrow the diagnostic possibilities Learn what questions must be done and what labs should be sought to further abbreviate the diagnostic conundrum.
