case_images: T1 a high signal intensity on T2 (Figure 1) and in CT scan a hypodense process extending on a height of 7cm and developing in the left posterior lumbar soft tissues at the height of L5 extending in the left sacral region with infiltration and osteolysis of the sacroiliac joint and the left sacral foramina with nerve root compression at this level. The patient underwent surgery with resection of a left paravertebral lesion + L5 and S1 laminectomy + partial resection of the intraductal portion of the tumor.
