The spinal cord was compressed by a diffusely enhanced epidural mass (white arrow) from C6 to T2, with isointensity on a T1-weighted magnetic resonance imaging (MRI) and low intensity on a T2-weighted MRI.. a: T1-weighted sagittal image.. b: T2-weighted sagittal image.. c: Gadolinium-enhanced sagittal image.

Gadolinium-enhanced magnetic resonance imaging (MRI) showed a diffusely enhanced epidural mass from C6 to T2 (Fig. 1, 2a).
T2-weighted sagittal MRI of the cervical spine.. a: The epidural mass (white arrow) compressed the spinal cord from C6 to T2 at the initial visit.. b: Significant reduction of the epidural mass was observed after the methylprednisolone pulse therapy for interstitial pneumonia.. c: Regrowth of the mass was observed from C5 to T3 at admission.. d: The mass had reduced, and there was no recurrence seven months after surgery.

Gadolinium-enhanced magnetic resonance imaging (MRI) showed a diffusely enhanced epidural mass from C6 to T2 (Fig. 1, 2a). MRI taken two months after the treatment showed a significant reduction of the mass (Fig. 2b). MRI showed regrowth of the mass from C5 to T3 (Fig. 2c). A follow-up MRI taken seven months after the surgery showed a decrease in the degree of dural thickening (Fig. 2d).
Intraoperative findings of the dura mater. The dura mater was found to be diffusely thickened and was compressing the underlying spinal cord.

Intraoperatively, we found diffusely thickened dura mater compressing the underlying spinal cord (Fig. 3).
Pathological findings of the surgically removed specimen. Hematoxylin and Eosin staining sections revealed fibrosis with infiltration of inflammatory cells, such as lymphocytes and plasma cells, surrounding relatively large vessels (original magnification x200).

The pathological examination showed fibrosis with infiltration of inflammatory cells surrounding relatively large vessels, findings seen in epithelioid granuloma and vasculitis (Fig. 4).
