(a and b) Demonstrate D2 anteromedullary enhanced tumor on T1 sequence. (c and d) Show D12-L1 lesion posterior located in the spinal canal displacing anteriorly the conus medullaris. (e and f) 10-year postoperative control MRI showing no recurrence on T1. (g and h) Shows no recurrence in T2. (i, j, k and l) demonstrate no tumor at D12-L2 level in 10-year postoperative control

Spinal magnetic resonance imaging (MRI) revealed multiple intradural extramedullary lesions, isointense on T1, hyperintense on T2, and fluid attenuated inversion recovery (FLAIR) sequences with intense contrast enhancement, at C2-C3, D2-D4-D5, and D12-L1 [Figure 1 shows no recurrence in T2.
(a and b) Shows sagittal multiple spine enhanced tumours. (c) Demonstrate coronal view of D10 tumor on T1-weighted sequence. (d and e) Presents axial view of "C" shaped D10 lesion. (f) Present 12-month postoperative T1-weighted contrast sequence. (g and h)Demonstrate 12-month postoperative control on T2-weighted images

D2, D4, D5, D8, D10, D11, L1, L3, L5, S1, and S2 [Figure 2]. D10 tumor was "C" shaped occupying 60% of the spinal canal without foramen invasion or bone destruction.

(a) Neoplastic proliferation of ependymal cells, eosinophilic cytoplasm and hyperchromatic nuclei with mild anisokaryosis and papillary structures. (b) Abundant myxoid matrix. (c and d) Immunohistochemistry were performed with antigen retrieval methods informing positive stain to GFAP and S-100 protein
