Osteoblastoma is a primary benign tumour which commonly presents in the younger population during the second decade of life. However, more aggressive osteoblastomas may present with features of aneurysmal bone cyst, and these can occur at uncommon locations.
We report the case of a 12-year-old child having an osteoblastoma on the left side of T11 with secondary aneurysmal bone cyst presenting with neurological deficits and myelopathic symptoms. Surgical debulking of the lesion with decompression laminectomy and posterior instrumentation of the spine was performed. The child is currently recovering well with improvement of neurological deficits.
DISCUSSION/CONCLUSION: Osteoblastoma with aneurysmal bone cyst of the thoracic spine is a rare condition with few reports in the literature, and surgical intervention with complete excision has been demonstrated here with recovery of neurological function.
成骨细胞瘤是一种常见于青少年人群的原发性良性肿瘤，通常发生在生命的第二个十年。然而，更具侵袭性的成骨细胞瘤可能表现出动脉瘤样骨囊肿的特征，这些肿瘤可能发生在不常见的部位。
我们报告了一例 12 岁儿童的病例，其左侧 T11 处患有成骨细胞瘤，伴有继发性动脉瘤样骨囊肿，表现为神经功能缺损和脊髓病症状。进行了病变的切除术、减压椎板切除术和脊柱后路器械固定术。目前患儿恢复良好，神经功能缺损得到改善。
讨论/结论：胸腰椎成骨细胞瘤伴动脉瘤样骨囊肿是一种罕见的疾病，文献报道较少，这里采用完全切除的手术干预方式，神经功能得到恢复。
