What sign, also seen in intracranial meningiomas, is present in this case, suggesting a dural origin?
Dural tail extending above and below the lesion.
A dural-based mass is located posterior to the thoracic cord, markedly compressing it. It is iso-intense to cord tissue on both T1 and T2 weighted images, and demonstrates vivid contrast enhancement. Dural tails are seen extending above and below the lesion.
