Yang, Oh, and Shim: Acute Spinal Cord Infarction: Diffusion-Weighted MR Imaging - Case Report -


Study Design

A case report.


We present a rare case of acute spinal cord infarction and usefulness of diffusion weighted MR imaging.

Summary of Literature Review

T1-weighted and T2-weighted images are often normal in a patient with acute spinal cord infarction.

Material and Methods

An 82-year-old presented with acute onset of paraplegia and urinary retention. His symptoms developed 6 days ago without any trauma. He had a history of vertebroplasty due to compression fracture of 12th thoracic vertebral body 6 years ago. There was no evidence of spinal cord compression on routine T1-and T2-weighted MRI.


In diffusion-weighted MRI, a high intensity signal intensity lesion in the spinal cord and conus medullaris was observed.


We report an example for the usefulness of diffusion-weighted image for early and accurate diagnosis of acute spinal cord infarction.

(A) T2-weighted sagittal image shows a strip like intramedullary high-signal intensity in the spinal cord. (B) and T1-weighted image shows no remarkable signal changes in the cord. (C) An axial T2-weighted image at the level of T12 show an symmetric intramedullary hyperintensy lesion. (D) An axial T1-weighted image at the level of T12 shows no abnormal signal changes.
