case_images: MRI of the patient's thoracolumbar spine. A: Sagittal MRI (T1-weighted) shows a posterior, extra-medullary, intracanal mass extending from T1 to T10.. B: Sagittal MRI (T2-weighted) displays a posterior, extra-medullary, intracanal mass extending from T1 to T10. The MRI signal characteristics suggest a compressive, fatty signal mass (blue arrow).. C: Axial MRI (T2-weighted) reveals a posterior, extra-medullary, intracanal mass compressing the spinal cord (blue arrow).

case_images: An MRI of the same spine region revealed a large, extradural, posteriorly located intracanal mass extending from T1 to T10, with signal characteristics suggesting a fat-containing lesion compressing the spinal cord (Figure 1).

case_images: The following surgical procedures were performed: complete excision of the mass using microsurgical instruments, repositioning of the laminar roof, layered closure of the surgical site, and placement of dual suction drains (Figure 3).
case_images: The postoperative image on day five (A) shows an infection at the surgical site, and the postoperative image taken on day 30 (B) shows the evolution of the wound.

case_images: On day five, a severe surgical site infection was developed, managed with ceftriaxone and amikacin, alongside the removal of certain sutures and local wound care (Figure 4).
