Magnetic resonance imaging of the thoracic spine. A, Sagittal T1-weighted imaging revealed an isointense anterior epidural mass extending from T3-T4 to T8-T9 (white arrows at the extremities of the mass), which compressed the spinal cord posteriorly, especially at the T5-T6 level. B, Sagittal T2-weighted imaging was helpful for delineation of the mass (white arrows at the extremities of the mass), which showed hyperintensity in this scan. The length was the same as that visualized with T1-weighted imaging, but the severity of the spinal cord compression was better visualized. C, Axial T2-weighted imaging revealed the epidural mass (white arrow) located in the anterior aspect of the spinal canal, compressing the spinal cord and obliterating the liquoric space.
