Spinal reconstruction for symptomatic thoracic haemangioma using a titanium cage

Abstract

Most vertebral haemangiomas are asymptomatic. A case of spinal reconstruction for symptomatic extraosseous thoracic haemangioma using a titanium cage is reported. Radiographs of the T11 vertebra demonstrated characteristic vertical striations. Magnetic resonance imaging and computed tomography showed spinal cord compression by extraosseous tumour extension. Several tumour feeding vessels were shown by angiography. Through a trans-pedicular biopsy, a histological diagnosis of cavernous haemangioma was made. Embolisation of feeding vessels was performed using coils before surgery. Laminectomy and subtotal vertebrectomy were performed by a single posterior approach. Rigid stabilisation of the spine was achieved with pedicle screw systems and a cage filled with an autogenous bone graft. Five months postoperatively, stabilisation of the spine was established without loosening of the cage or pedicle screws. Clinical symptoms were improved.
