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).

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).

The patient underwent posterior L2 vertebrae tumour resection and biopsy with spinal canal decompression, autogenous iliac bone graft fusion and internal fixation (Figure 2).
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).

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).
