Preoperative thoracic MRI. A heterogeneous epidural posterior mass compressing the thoracic cord between Th5 and Th8 was revealed at admission. Sagittal view of the heterogeneous isointense mass of the T1-weighted image (a), heterogeneous hyperintense mass of the T2-weighted image (b), and enhanced mass of the fat-suppression image by short-T1 inversion recovery (STIR) (c). Axial view of the epidural mass of the T1-weighted image (d), T2-weighted image (e), and STIR image (f). This tumor had lipomatosis in its upper segment (arrowhead).

T1-weighted imaging and slightly hyperintense on T2-weighted imaging (Figure 1). These clinical courses and radiological findings suggested epidural hematoma.
Postoperative thoracic MRI (seven days after surgery). Postoperative MRI showed the complete resection of the tumors. Sagittal view of the T1-weighted image (a) and T2-weighted image (b).

The complete resection of these extremely hemorrhagic adipose components made compressive dura matter swollen (Figure 2).
Histopathological analysis of the resected tumors. The spinal angiolipoma consists of both mature fatty tissue and abnormal proliferating vascular elements with thin or expanded walls, which usually contain fibrin thrombi (hematoxylin and eosin stained; magnification: (a) x40 and (b) x100).

Nonfiltrating spinal angiolipoma was diagnosed and confirmed by pathology (Figure 3).
