case_images: Magnetic resonance imaging (MRI) of the thoracic spine revealed a well-circumscribed isotense T1/bright T2 homogeneously enhancing intradural, extramedullary mass centered at the T5-6 level eccentric to the right [Figure 1a and b]. A portion of this mass in the form of a dumbbell shape extended through the right T5-6 neural foramen [Figure 1b], which was otherwise normal in dimension.

case_images: An extradural component of the tumor was seen on the right T5-6 foramen [Figure 2a]. Opening the dura showed an intradural and extramedullary mass with a clearly identifiable cleavage caudal and cephalad of the tumor without attachment to the dura [Figure 2b].
