The current study aimed to investigate the imaging manifestations of vertebral aneurysmal bone cyst (ABC), and examine the clinical value of interventional embolization. Imaging examinations of 5 patients with pathologically confirmed spinal ABC were analysed and arterial angiography and embolization were performed prior to surgery. The cases in this cohort exhibited different degrees of intrusion into the vertebral arch and spinous and transverse processes. Lesions that protruded into the spinal canal resulted in compression of the thecal sac and spinal cord. Enlargement of arteries was detected by digital subtraction angiography and decreased significantly following embolization. Blood loss during surgery was also significantly reduced. Preoperative embolization of ABC reduces bleeding and allows for easy access to tissue, which is of great clinical value.
