Aneurysmal bone cyst (ABC) is a benign bone lesion and commonly affects young adolescents. It usually grows rapidly with hypervascularity. In the spine, it can cause extensive bone destruction and compress neural structures with eventual vertebral collapse. Operative management of such a lesion may be complicated by profuse hemorrhage. Herein, we report a 15-year-old boy who had an acute exacerbation of spinal cord compression because of an ABC in the upper thoracic region. With a two-staged operation that complicating with profuse intraoperative bleeding, decompressive curettage and stabilization of the vertebral column were assured. However, abrupt neurologic deterioration occurred because of rebleeding with spinal cord compression 1 month postoperatively. Secondary decompressive curettage and following local radiotherapy were undertaken to cure the disease. Neurological recovery and healing of spinal ABC could be expected if the lining of a cyst had been totally removed. At the 18-month follow-up examination, he was neurologically intact and without any backache, leg pain or gait disturbance.

Aneurysmal bone cyst (ABC) of the spine can cause acute spinal cord compression in young patients. We report the CT and MRI findings in a histology-proven case of spinal ABC presenting with sudden paraplegia. Typical features of a spinal ABC at the thoracic level with considerable extension into the posterior epidural space and cord compression were demonstrated. Special note was made of the disproportionately large longitudinal extent of the epidural component of the lesion. Associated vertebral collapse was absent. A fracture of the overlying cortex had probably allowed the lesion to decompress and track along the epidural space without significantly jeopardizing integrity of the osseous structures. This case illustrates a less frequently recognised mechanism of acute spinal cord compression by ABC.

Aneurysmal bone cysts (ABCs) are benign, highly vascular osseous lesions characterized by cystic, blood-filled spaces surrounded by thin perimeters of expanded bone. Children and young adults are most often affected by spinal ABCs; more than 75% of patients are younger than 20 years old at presentation. Although ABCs have been documented in all areas of the axial and appendicular skeleton, ABCs of the spine present unique challenges due to the risk of vertebral destabilization, pathological fracture and vertebral body (VB) collapse, and neurological compromise. The authors describe the case of an 8-year-old child who presented with low-back pain and was subsequently found to have a lumbar ABC causing vertebra plana of the L-3 VB. They also review the literature on ABCs of the spine. This case highlights the importance of considering an ABC in the differential diagnosis when vertebra plana is seen in pediatric patients.

Aneurysmal bone cyst (ABC) is defined as a benign lesion of bone containing blood-filled channels divided by soft-tissue septa and mostly diagnosed in children and adolescents. In the present study, the case of a 7-year-old girl with spastic paraparesia and left foot drop was investigated. Spinal imaging revealed a large lytic mass in the posterior elements of the T2 vertebral body, which resulted in the partial collapse of the T2 vertebral body, a T1 to T3 dislocation, and a spinal sagittal imbalance. The patient underwent a two-stage surgical procedure including an anterior T2 corpectomy, T1/T2 and T2/T3 discectomy, anterior instrumentation, posterior total tumor resection, and posterior fixation with laminar hooks. Postoperative imaging demonstrated cord decompression and good spinal alignment. Although a spinal ABC is a rare entity, it can occur in any segment of the spinal column and cause cord compression and spinal instability. Thus, proper treatment planning is crucial for total tumor resection to avoid tumor recurrence and correct spinal imbalance.
