| 目的 探讨继发性动脉瘤样骨囊肿(SABC)的影像学表现。 方法 回顾性分析经手术或病理活检证实的26例SABC的影像学资料。 结果 26例SABC患者接受X线及CT检查,病灶表现为不同程度膨胀性骨质破坏,14例位于长骨,9例为偏心型,5例见骨皮质破坏。23例患者接受MR检查,19例见囊腔,11例见液-液平面,9例见囊间隔,7例瘤周见骨髓水肿。 结论 SABC 的MRI表现复杂多样,因原发病变的不同而有所差别,但多数仍具有动脉瘤样骨囊肿的共性MRI特点。结合X线、CT检查有助于提高术前诊断的准确率。 |

| Objective To observe the image manifestations of secondary aneurysmal bone cyst (SABC). Methods Totally 26 patients of SABC were retrospectively analyzed. The diagnosis was further evidenced by pathological findings either from open surgery or minimally invasive needle biopsy. Results All 26 patients underwent X-ray and CT examination, expanded and lytic bony destruction were observed in all 26 cases.Fourteen lesions located at long tubular bone, 9 cases were eccentric and visible cortical bone defect was observed in 5 cases. Twenty-three cases were imaged with MR. Multiple cystic spaces were observed in 19 cases, fluid-fluid levels in 11 cases, internal septations in 9 cases and surrounding bone marrow edema was found in 7 cases. Conclusion MRI manifestations of SABC were various and complicated, due to the variation of the original diseases. However, most lesions showed collective MRI characters of aneurysmal bone cyst. Accurate pre-operative diagnosis can be facilitated by generalizing the findings from X-ray and CT image. |
