摘要

Chondrosarcoma is a fairly common malignant primary bone tumor, it affects predominently the middle-aged population. The pelvis and ribs are the most common sites, followed by the proximal end of the femur. From 1980 to 1986. eighteen surgically proved cases of chondrosarcoma were reviewed. We acknowledge that conventional tomography will demonstrate fine details of the lesion if plain film shows indistinct details; however, when the lesion is large, aggressive, with poor margins, and having soft tissue invasion, computed tomography is superior in delineating anatomic extent-especially anatomically complex regions such as pelvis, intralesional calcification, and soft tissue extension due to its high resolution power and axial view. Therefore, better surgical planning can be carried out and the rate of recurrence can be reduced.

並列摘要

軟骨肉瘤是一種比較常見的惡性骨瘤，好發於中年人，較常發生於骨盆和肋骨。另外，股骨上部也是常發生的部位。由民國69年至民國75年間，我們覆閱了18位經過手術，並經病理證實為軟骨肉瘤之病倒及其放射線檢查，發現當常規素片未能提供精確的診斷資料時，傳統的斷層攝影（conventional tomography）能夠提供更多有價值的資料；然而當病灶比較大，較具侵潤性（aggressive），或比較差的邊緣，或有軟組織侵犯的情形，由於電腦斷層攝影（CT）具備了優良的橫切面解析影像條件，對於病灶的邊緣情形，鈣化與侵犯的範圍皆能清楚的偵測出來。因此，更好的手術計畫（surgical planning）得以進行，從而可避免不完全的切除及病灶的再復發。
