MR imaging showing preoperative (A, B, C) and postoperative (D, E) imaging characteristics of the T11 intradural intramedullary spinal mass. (A) Preoperative T1-weighted image without gadolinium enhancement showing the approximately 1.7 cm lesion. (B) Preoperative T1-weighted image with gadolinium enhancement showing homogeneous enhancement of the lesion, which is not significantly enhancing over the non-contrasted T1 scan. (C) Preoperative T2-weighted image showing syrinx formation both rostral and caudal to the lesion. (D, E) Postoperative T1- and T2-weighted images, respectively, showing near-complete resection of the mass with postoperative intramedullary cavity.
