case_images: Preoperative coronal reconstructed (A) and sagittal bone window CT (B) show multiple irregular hyperdense lesions in the vertebrae of thoracic, lumbar and sacrococcyx, iliac bone. The sagittal soft-tissue window CT shows the soft tissue density mass in the spinal canal at L2 level (C) and the corresponding axial CT suggests Grade 2-3 epidural spinal cord compression (ESCC) (D).

case_images: Subsequent abdominal contrast-enhanced computed tomography (CT) scans showed nodular changes in bilateral adrenal glands and multiple irregular hyperdense shadows in the thoracic vertebrae, lumbar vertebrae, iliac bone, and femur (Figure 1).
case_images: Postoperative anteroposterior radiograph following instrumented stabilization (A). Postoperative lateral radiograph following instrumented stabilization (B).

case_images: fig2-21514593221111357
case_images: The patient underwent posterior L2 vertebrae tumour resection and biopsy with spinal canal decompression, autogenous iliac bone graft fusion and internal fixation (Figure 2).
case_images: Hematoxylin eosin (HE) staining resulted in a diagnosis of the tumor as adenoid cystic carcinoma (A). P63 (+), CK7(+), Calponin (+), PCK(+), EMA (+), and SMMHA (+) were suggested (B).

case_images: fig3-21514593221111357
case_images: Haematoxylin eosin staining of the sample indicated a histological type of adenoid cystic carcinoma (Figure 3A) while immunostaining revealed P63 (+), S-100 (-), CD117 (-), SMMHA (+), Calponin (+), EMA (+), and CK7(+) (Figure 3B).
