Figure captions
Figure 1: Sagittal T1W image shows well-defined iso to hypointense lesion extending from the lower level of T10 vertebral body to L2 vertebral level in extramedullary region (red arrow). The lesion is severely compressing the spinal cord. The vertebral bodies show normal signal intensity. Intervertebral disc space is well maintained and no prevertebral collection can be appreciated. T1W, T1-weighted
Figure 2: Sagittal (A) and axial (B) T2W images show well-defined, heterogeneous, extra-medullary, iso to hyperintense lesion (red arrow) extending from T10 to L2 vertebral levels, compressing and displacing the spinal cord anteriorly. No obvious erosion of the vertebral body is seen. T2W, T2-weighted
Figure 3: Sagittal STIR image showing extra-medullary lesion (red arrow) extending from T10-L2 levels with high signal intensity to the vertebral marrow which is compressing and displacing the spinal cord anteriorly. STIR, short tau inversion recovery
Figure 4: A 15 x 1 cm grey to white-colored lesion which was soft to firm in consistency
Figure 5: Histopathology (hematoxylin and eosin, x 200) revealing diffuse proliferation of intermediate-sized atypical lymphoid cells infiltrating into the fibrocollagenous tissue. Few of the cells show nuclear irregularity with prominent nucleoli. Small lymphocytes are also seen in the adjacent area.
