Aneurysmal Bone Cyst of the Spine Experience at a Single Tertiary Hospital

Abstract

Objective Aneurysmal bone cyst (ABC) is a benign osseous tumor, with a local aggressive nature. It is rarely seen in the spine which causes a delayed diagnosis and treatment. The aim of this study is the treatment results of ABC of the spine in our clinic and investigate the current treatment options. Material and Method A search of the ABCs of the spine between 2005 and 2019 years was conducted on online hospital database system. There were 6 patients (4 male, 2 female), with a duration of symptoms until treatment 2.7 years. Results Two patients were treated with curettage, posterior instrumentation was added due to iatrogenic instability after tumor removal in three patients, and selective arterial embolization was used to control the tumor growth in a patient with comorbidities, and surgery was planned for the patient after treatment of comorbidities. Conclusion Embolization can be used in patients without neurological symptoms and in the absence of deformity. Curettage and bone grafting are the viable surgical treatment method in stage 2 lesions. However more extensive surgery may be necessary in patients with spinal instability, such as posterior instrumentation and fusion, and en bloc resection with neural structure sacrifice in recurrent or primary stage 3 lesions.
