摘要

軟骨肉瘤在兒童的發生率非常低。我們提出一位3歲男童，在腸胃炎住院期間，腹部素片意外發現左側腸骨軟骨肉瘤的案例。骨盆腔電腦斷層攝影及磁振造影顯示在左側腸骨有一個含有軟骨成分的多葉狀腫瘤。病患接受了腫瘤廣泛切除，病理組織檢查的最終診斷為低度傳統軟骨肉瘤。即使一個兒童者，在腸骨出現一個大型的礦化腫瘤，並有軟骨成分時，軟骨肉瘤應列入鑑別診斷中。據我們所知，這是第一個包含電腦斷層攝影及磁振造影像，討論五歲以下病患低度軟骨肉瘤的病例報告。

Chondrosarcoma is very rare in children. We present a case of a 3-year-old boy with a pelvic chondrosarcoma incidentally discovered on a plain abdominal radiograph. Pelvic computed tomog raphy (CT) and magnetic resonance imaging (MRI) showed a lobulated bone tumor with chondroid components in the left iliac bone. The child underwent wide excision of the tumor. Pathology examination confirmed a final diagnosis of low-grade conventional chondrosarcoma. When a large mineralized tumor with a chondroid component involves the pelvic bone, chondrosarcoma should be considered in the differential diagnosis even in a child, despite the low incidence of the tumor in young children. To our knowledge, this is the first case report of CT and MRI evidence of a low-grade iliac chondrosarcoma in a patient under the age of 5 years.
