Computed Tomography Demonstration and Diagnosis of Calcaneus Intraosseous Lipoma: A Case Report

跟骨骨內脂肪瘤之電腦斷層攝影:病例報告

摘要


跟骨骨內脂肪瘤是一種少見原發陸良性腫瘤,通常以長骨之骨骺端較易發生尤其股骨和腓骨前端骨,以及少許發生於跟骨。男女之比例無多大區別,其發生年齡由五歲至七十歲,常見於四十歲以後。 跟骨骨內脂肪瘤之診斷,首先應以常規放射線攝影,發現有病灶之後,才進一步使用電腦層攝影。因為常規放射線攝影之影像較難和原發性骨內囊腫瘤作區別診斷,而電腦斷層攝影可利用病灶部位電腦斷層衰減係數來作正確診斷,因為脂肪係數為-20~-120(Hounsfield scale)這樣的病患可避免不必要開刀。

並列摘要


Intraosseous lipoma of the calcaneus is an uncommon primary benign tumor of the bone which has the characteristic radiographic appearance of a radiolucent lesion with a sharply defined sclerotic outline. For such a lesion, computed tomography (CT) is very helpful in depicating the lesion by measuring it's attenuation numbers.
