Extraosseous spinal epidural plasmocytoma associated with multiple myeloma: Two case reports

Figure 2 Magnetic resonance imaging showed a posterior epidural mass located from Th11 to L1. A: Sagittal T1-weighted imaging (T1WI); B: T2-weighted imaging (T2WI); C: T2-weighted fat-saturation imaging; and D: Axial T2WI showing an epidural mass compressing the spinal cord. Diffuse patchy areas of isointense signal on T1WI and slightly hyperintense signal on T2WI were seen in all vertebrae; E: Computed tomography showed multifocal osteolysis and clearly defined cortical margins of the vertebrae from Th11 to L1. The Th8 and Th9 vertebral bodies had collapsed, indicating a compression fracture caused by myeloma-induced bony destruction.
