中文摘要 | 動脈瘤樣骨囊腫佔1.4%之所有原發性骨骼腫瘤和15%於所有脊椎原發性骨骼腫瘤芴其發生是良性芴並且經過刮除術後極少有復發之機率。 其發生年齡由10至20歲芴平均年齡為14至16歲芴女性多於男性芴於臨床上其會產生局部痛覺芴尤其於晚上芴腫脹或腫塊和病理性骨折(10%)芴另外如果發於脊椎會造成脊髓受到壓迫。 其最常侵犯部位為長骨骨幹舷端部(51%)特別於股骨末端芴另外脊椎(15%)的背後成份芴並有少許侵犯跟骨、頭骨、髖骨、等芴於常規放射線攝影所顯示為擴張離心的放射透射或肥皂泡沫性病灶和會侵入鄰近的軟組織芴另外芴會有病理性骨折和少有骨膜反應芴但無鈣化。 新光吳火獅紀念醫院內1993年3月至2005年3月共收集了6例疑似動脈瘤樣骨囊腫年齡由8歲至47歲芴平均年齡為22.5歲緻男性4位芴女性2位。這些病患都接受常規放射線攝影芴其中2例接受電腦斷層攝影芴2例接受磁共振造影芴4例則接受核子醫學骨骼掃描芴並且經過開刀和病理組織診斷為動脈瘤樣骨囊腫。因此我們將其影像特徵和回顧文獻報告芴提供給大家參考指教。 |
英文摘要 | Aneurysmal bone cyst (ABC) accounts for 1.4% of all bone tumors and 15% all primary spinal tumors. Radiography shows an eccentric ballooned or aneurysmal, expanded radiolucency, mostly in the metaphysis of long bone. The margin of ABC is usually well circumscribed with or without a scle-rotic rim. Trabeculation is sometimes seen in the lesion but without significant mineralization or cal-cification. In spine, it demonstrates a purely lytic lesion in the posterior elements and body. Six patients in our hospital with primary ABC with histopathologic confirmation were studied with con-ventional radiographs, contrast-enhanced computed tomography study, contrast-enhanced MRI study and nuclear medicine bone scintigraphy separately. All cases showed expansile radiolucent lesions with soup bubble appearance and one case with patho-logic fracture. Relevant literature was also reviewed. We discuss and emphasize characteristic imaging features and clinical course of ABC. |
