A 9-year-old girl with a solid variant of an aneurysmal bone cyst in the 3rd lumbar vertebra showed a good response to low-dose radiation as the only treatment. The solid variant of aneurysmal bone cyst is thought to be a reactive response to intraosseous hemorrhage and is also called giant cell reparative granuloma or giant cell reaction. These lesions in the jaw and the short tubular bones of the hands and feet frequently recur after surgery. Aneurysmal bone cysts of the spine also show a fairly high recurrence rate after incomplete resection or radiation therapy. However, 7 previous cases of the solid variant of aneurysmal bone cyst in the spine and this case did not show recurrence after a mean follow-up period of 45 months. This difference in behaviour suggests that the solid variant should be recognized before surgery as being distinct from conventional aneurysmal bone cysts, especially in the spine.
一名9岁女孩，第三腰椎患有骨囊肿实性变种，仅接受低剂量放射治疗便取得了良好疗效。骨囊肿实性变种被认为是对骨内出血的一种反应性病变，也被称为巨细胞修复性肉芽肿或巨细胞反应。颌骨以及手足短管状骨的这些病变在手术后经常复发。脊柱骨囊肿在不完全切除或放射治疗后也显示出相当高的复发率。然而，此前7例脊柱骨囊肿实性变种病例以及本病例在平均45个月的随访期后均未复发。这种行为上的差异表明，在手术前应认识到实性变种与传统骨囊肿不同，尤其是在脊柱中。
