Note:—Level indicates craniocaudal extension described as the number of vertebrae where mass was present; Epidural, location of masses either anterior (Ant) or posterior (Post) epidural space; T1WI, T1-weighted MR image; T2WI, T2-weighted MR image; CE, contrast-enhanced MR image; A, cystlike mass with T1 hyperintensity; B, cystlike mass with T1 isointensity; C, solid hypervascular mass; D, epidural hematoma; Iso, isointense; HM, homogeneous signal intensity; HT, heterogeneous signal intensity; Peripheral, peripheral enhancement.
