T2MRI of the entire spine showing an abnormal signal in the spinal canal and a hyperintensity of 5 mm in the anterior spinal canal likely intradural and extramedullary at the lower T9 level.

Magnetic resonance imaging of the entire spine without contrast (Figure 1) revealed more of the abnormal signal that extends from the clivus to the spinal canal, perhaps related to subarachnoid hemorrhage, but a mass could not be excluded without intravenous contrast. T2-weighted images measuring 5 mm in diameter was observed in the anterior spinal canal at the lower T9 level, likely to be intradural and extramedullary in location (Figure 1). The diagnostic spinal angiogram did not show any angiographically evident vascular malformations in the spinal cord.
T2 MRI of the entire spine demonstrating a significant increase in the size of the previously noted lesion surrounded by a rim of a decreased gradient signal suggesting a hemorrhagic component and a likely picture of cord edema at T9-T10.

A thoracic cord MRI (Figure 2) demonstrated a lesion of 0.8 x 1.1 x 1.1 cm within the spinal canal at the level of
Postoperative MRI sagittal view showing T8-T10 laminectomy with mild dilatation of the cord and a T2 signal abnormality within the cord from the T7-8 through the T10-11 levels.
