case_images: Mass lesion with hypointensity in T1-weighted images (arrow) (A), with slightly lower signal than CSF in T2-weighted images (arrow) (B), and slightly heterogeneous gadolinium-enhanced T1-weighted images (C) upon sagittal thoracic spine MRI. CSF : cerebrospinal fluid.

case_images: T7-8 vertebral body levels. This lesion was hypointense upon the T1-weighted images (Fig. 1A), with a slightly lower signal than the cerebrospinal fluid (CSF) on the T2-weighted images (Fig. 1B), and slight heterogeneous staining on the gadolinium-enhanced T1-weighted images (Fig. 1C).
case_images: Mass displacing the spinal cord to the right side in the axial plane in the T2-weighted (A) and fat suppression T1-weighted enhanced (B) images uponthe MRI.

case_images: Additionally, it was observed that the spinal cord was displaced to the right side due to the mass (Fig. 2).
case_images: Extradural hemorrhagic mass located in the operating field (arrows) (A) and its gross finding after total removal (B).

case_images: The histopathological examination revealed a cavernous hemangioma, composed of large dilated blood-filled vessels lined with flattened endothelium (Fig. 4).
