摘要
目的通过对盆壁肿瘤的多层螺旋CT表现的分析,提高对其CT诊断的认识。方法回顾性分析20例盆壁肿瘤的多层螺旋CT表现,其中转移瘤10例,神经源性肿瘤5例(其中神经鞘瘤2例,神经纤维瘤1例,神经纤维瘤病2例),软骨肉瘤2例,脊索瘤1例,骨巨细胞瘤1例,骨软骨瘤1例。结果盆壁肿瘤的主要征象包括骨质破坏、软组织肿块,转移瘤以骨质破坏为主;较有特征性的表现有神经源性肿瘤伴骶孔扩大,软骨肉瘤有多种形态钙化;脊索瘤位于下部骶椎;巨细胞瘤骨质破坏伴骨嵴;骨软骨瘤为菜花状结节。结论对盆壁肿瘤的诊断,多层螺旋CT轴位图像结合三维重组图像可以较好的显示肿瘤形态、大小、范围及肿瘤内部结构、与邻近组织器官结构关系,从而作出合理的诊断。
Objective To evaluate the value of multi-slice CT （MSCT） in diagnosing pelvic wall tumors. Methods MSCT of 21 cases of pelvic wall tumors including metastasis （10）, neurogenic tumor （5）, chondrosarcoma （2）, chordoma （1）, a- neurysmal bone cyst （1）, giant cell tumor （1）, and osteochondroma （1） was retrospectively analyzed. Results CT appearances of pelvic wall tumors include bony destruction and soft tissue masses. Common features were bone destruction in metastasis, expansion of the neuroforamen in neurogenic tumor, pleomorphic calcification in chondrosarcoma, lower sacral vertebral location of chordoma, iliac crest bone destruction in giant cell tumor, cauliflower-like nodules in osteochondroma. Conclusion MSCT with three-di- mensional volume rendering demonstrates well the tumor shape, size, extent, internal structure and relationship with the surrounding organs to aid diagnosis of pelvic wall tumors.
