FIGURE 1
Sagittal magnetic resonance imaging of the spine shows a soft tissue lesion (red arrows) that involves the retrocrural space at the level of D5‐D12 with polycyclic contours on hypointense T1 (A), hypointense T2 (B), and hyperintense T2 STIR (D) with heterogenous gadolinium enhancement (C)
FIGURE 2
FIGURE 2
Axial magnetic resonance imaging of the spine at the level of D8‐D9 shows a soft tissue lesion (red arrows) involving the aorta‐vascular structures in the retrocrural space extending to the spinal cord via the left intervertebral foramen with cord compression (blue Asterix), on hypointense T2 (A) and gadolinium enhancement (B)
FIGURE 3
FIGURE 3
Axial magnetic resonance imaging of the spine shows a soft tissue lesion (red arrows) involving the aorta‐vascular structures in the retrocrural space at the level of D9‐D10, extending to the spinal cord via the left intervertebral foramen with cord compression (blue Asterix), on hypointense T2 (A) and gadolinium enhancement (B)

Histologic aspect and immunohistochemical characteristics of extramedullary plasmacytoma involving the retrocrural space showing atypical plasmocytic cells with variable degree of differentiation (A) positive for anti CD38 (B), anti CD138 (C), and anti‐Lambda (D)
