case_images: Sagittal (a) and axial (b) sections of a spinal cord magnetic resonance imaging on T1-weighted image with injection of Gadolinium showing a posterior epiduritis ranging from T5 to T10 responsible for compression of the spinal cord.

case_images: The thoracic magnetic resonance imaging (MRI) [Figure 1] showed posterolateral epiduritis between the T5 and T10 levels contributing to marked cord compression; it was isointense on T1, slightly hyperintense on T2-weighted images, and markedly enhanced with contrast. The patient underwent and emergent T5-T10 laminectomy.
case_images: Pathological examination showing a diffuse infiltration of inflammatory cells within the fibrofatty tissue, with presence of 50 immunoglobulin G4 (IgG4)+ cells/high-powered field and 50% IgG4+/IgG cell ratio.

case_images: The pathological examination [Figure 2] revealed diffuse infiltration of inflammatory cells within the fibrofatty tissue, accompanied by 50 IgG4+ cells/HPF and 50% IgG4+/IgG cell ratio.
