Case 10, an epidural hematoma (type D).A, Sagittal T2-weighed spin-echo MR image demonstrates an ill-defined lesion with heterogeneous low and high signal intensity at the posterior epidural space of C5-C7.B, On sagittal noncontrast T1-weighed spin-echo MR image, there is high signal intensity in that lesion, suggestive of a hematoma.C, On sagittal postcontrast T1-weighed spin-echo MR image, the lesion shows heterogeneous enhancement.D, On histologic examination, most of the area is an organized thrombus. There are scattered small foci of large, dilated, blood-filled vessels lined by flattened endothelium, which represents a cavernous hemangioma (H&E, × 100).
