Sagittal view of spine MRI showing A) T1-weighted images, B) T2-weighted images, and C) gadolinium-enhanced images. Hypertrophied dura is seen in the anterior and posterior canal, with severe compression of the spinal cord from T2 to T10.

Head MRI showed no abnormalities, but spinal MRI showed a hypointense mass-like lesion (hypertrophic dura) compressing the spinal cord and extending from T2 to T10 on both T1-weighted and T2-weighted imagery (Fig. 1A-C).
A) Intraoperative photograph showing the slight adhesion between the dura mater and the arachnoid. B) Intraoperative photograph showing the duraplasty conducted from T2 to T10. C, D) Photograph showing the resected sections of thickened dura.

T2-T10. The adhesion between the dura mater and the arachnoid was slight, and the resection was relatively easy (Fig. 2A). The resulting extensive defect in the dura mater was repaired by Gore-Tex patch (Fig. 2B). The excised dura was thickened, measuring almost 17 cm in length and 6 mm in width at the widest point (Fig. 2C, D).
Postoperative sagittal view of spine MRI showing A) T1-weighted image, and B) T2-weighted image. Spinal atrophy was improved.

There have been no signs of recurrence in the 2 years following surgery (Fig. 3A, B).
