case_images: Sagittal unenhanced T1 weighted MR images: A) shows a homogeneous well-defined, ovoid epidural mass with isointense signal relative to the spinal cord, with a <<wafting silk>> sign. Sagittal T2-weighted images; B) shows a heterogeneous hyperintense epidural mass. Sagittal contrast-enhanced T1-weighted images; C) shows homogeneous intense enhancement of the mass

case_images: T9 to T10 with a lobulated contour realising a <<wafting silk>> sign (Figure 1), compressing and flattening the dorsal spine without infiltrating it, and widening the left foraminal region and eroding the body of the vertebrae with a dumbbell-shaped morphology in transverse images (Figure 2), compressing the nerve root. The mass showed isointense signal in T1-weighted images and hyperintense signal in T2-weighted images, with intense contrast enhancement.
case_images: Transverse unenhanced: A) and contrast-enhanced; B) T1-weighted MR images show an epidural mass with homogenous intense enhancement, extending into and widening the left inter-vertebral foramen with a typical dumbell-shaped morphology and a bone erosion of vertebral body

case_images: Histopathological examination of the mass confirmed its vascular origin, with many small cavernous vessels and thick hyalinised walls, without malignant cells (Figure 3).
