Osteoblastoma is a rare and benign osteoid-producing primary bone tumor that affects mainly the long bones. 36% of these tumors are observed around the spine and the vast majority arises around the posterior.
This report describes a case of C3-4 osteoblastoma occurring in a 5-year-and-8-month-old Han Chinese child. The pathophysiology of symptom development, evaluations, and management are presented. Because of the close proximity of the osteoblastoma to the vertebral artery canal, the artery suffered a minor laceration intraoperatively. Hemostatic gelatin sponges were used to compress the bleeding site instantly and a tricortical iliac crest fixed with a screw was also used to add pressure to the gelatin sponges. Fusion on the other side was also used to stabilize the spine. To the best of our knowledge, this is the first report of a case of osteoblastoma at C3-4 with artery injury intraoperatively.
This case delineates the difficulties in diagnosing this tumor, the challenges and problems encountered during its surgical management, and the favorable prognosis after adequate treatment.
骨母细胞瘤是一种罕见的良性骨样组织生成性原发性骨肿瘤，主要累及长骨。其中36%的肿瘤发生在脊柱周围，且绝大多数发生在脊柱后部。
本报告描述了一名5岁8个月大的汉族儿童发生的C3 - 4节段骨母细胞瘤病例。介绍了症状发展的病理生理学、评估和治疗情况。由于骨母细胞瘤紧邻椎动脉管，术中该动脉受到轻微撕裂。立即使用止血明胶海绵压迫出血部位，并使用一枚螺钉固定的三层髂嵴对明胶海绵施加额外压力。另一侧也进行了融合以稳定脊柱。据我们所知，这是首例C3 - 4节段骨母细胞瘤术中出现动脉损伤的病例报告。
本病例阐述了该肿瘤诊断的困难、手术治疗过程中遇到的挑战和问题，以及充分治疗后的良好预后。
