Case 2. Sagittal T1-weighted (a), sagittal T2-weighted (b), sagittal fat suppressed T2-weighted (c) MRI images showing a spindle shaped epidural mass extending from T2 to T4. The mass is hypointense in T1, with inhomogenous fat signals in peripheral region, hyperintense in T2 weighted imaging. The fat signals were suppressed in fat suppressed T2. Signs of thoracic and lumbar degeneration including thickening of ligamentum flavum in T10–T12 sections and disc herniation in multiple lumbar disc. Axial T2-weighted (d, e) images showed the tumor extends into bilateral neural foramen and compresses the spinal cord anteriorly. The mass is low signal in DWI (f) and high signal in ADC (g), no obvious diffusion restriction was observed. In sagittal fat suppressed T1-weighted post-contrast (h) image, the mass was significantly enhanced. The dynamic contrast enhanced curve (i) showed the rapid rising wash-in phase and wave-like washout phase without obvious decline. A grey reddish mass was resected after surgery (j). Histological sections (k) shows tumor is composed of abundant vascular channel filled with red blood cells and fibrin thrombi and mature adipose tissue
