Although simple bone cysts in children have been described by many authors, there has been only one previous report of more than one lesion in a single patient. We describe an 11-year-old boy with symptoms caused by a cyst in the proximal femur. Following steroid injection of the cyst, a pathological fracture occurred and was treated by immobilization in a cast. A year later, a pathological fracture occurred through a cyst in the proximal humerus. This was treated in a sling. Steroid injection of both lesions was performed when the cystic areas persisted, and both cysts subsequently healed. This case demonstrates that simple bone cysts are not always solitary lesions and that patients with these cysts should be carefully monitored for recurrence following treatment.
尽管许多作者都描述过儿童单纯性骨囊肿，但此前仅有一篇关于单一患者出现不止一个病灶的报道。我们报告一名11岁男孩，其股骨近端囊肿引起了症状。囊肿注射类固醇后发生了病理性骨折，通过石膏固定进行治疗。一年后，肱骨近端的一个囊肿又引发了病理性骨折，此次采用吊带治疗。当囊肿区域持续存在时，对两个病灶都进行了类固醇注射，随后两个囊肿均愈合。该病例表明，单纯性骨囊肿并非总是孤立性病灶，对于患有这些囊肿的患者，治疗后应密切监测复发情况。
