软骨粘液样纤维瘤的CT诊断

目的:探讨软骨粘液样纤维瘤的CT表现特征及诊断价值。方法:结合文献回顾性分析4例经手术病理诊断的软骨粘液样纤维瘤的CT影像征象。结果:其CT表现有以下特点:①肿瘤呈圆形或卵圆形多囊或单囊的透光区,呈偏心性生长。②病灶边缘清楚、锐利,与周围正常骨分界明显,周围骨质有硬化。③病变一般不穿通骨膜,很少有骨膜反应。④骨质缺损区内可有钙化。⑤病灶内的骨性间隔较粗大而致密。结论:CT扫描可清楚观察肿瘤的边缘及内部结构,可以很明显地与多囊性骨囊肿、巨细胞瘤及良性软骨母细胞瘤鉴别。

CT diagnosis of chondromyxoid fibroma

Objective To study the CT imaging characteristic manifestation and diagnosis of chondromyxoid fibroma.Method A retrospective analysis of the imaging features of 4cases with chondromyxoid fibroma diagnosed by surgical pathology with reference to medical literature.Results The CT features were divided into five patterns:A tumor with multiple cyst and round or oval shape lu-cent areas.B tumor with relatively well-defined margin and sclerotic reaction.C tumor without destroying periost and following pe-riosteal response.D Calcification within the destructive lesion.E.Rough and compact bone intervals in the destructive lesion.Con clu-sion CT scan is better demonstrated the edges and internal conditions of the tumor,and it allows differentiation of Chondromyxoid fibro ma,multifocal bone cyst,giant cell tumor of bone,chondroblastoma.
