为提高脊索瘤的 CT 和 MRI 诊断的正确性。本文分析了31例经手术病理证实的脊索瘤患者的临床与 CT 和 MRI 表现(男15例,女16例),年龄最大78岁,最小24岁,平均42.16岁。其中19例位于颅内,2例位于颈椎,1例位于腰椎,9例位于骶尾椎。29例行 CT 检查,29例行 MRI 检查,CT和 MRI 同时检查27例。结果:31例 CT 和 MRI 均显示软组织肿块,29例骨质破坏(93.55%),16例钙化(51.61%)。肿瘤形态呈不规则形、类圆形。增强扫描大部分病灶呈轻度强化。本组29%发生在骶尾骨。结论:脊索瘤的典型表现为斜坡或骶尾部软组织肿块伴骨质破坏和病灶内钙化。CT 和 MRI 检查对脊索瘤的诊断及对肿瘤侵犯的范围有很大帮助。
To improve the diagnosis of chordoma CT and MRI correctness. In this paper, clinical and CT and MRI findings of 31 cases of chordoma confirmed by surgery and pathology (15 males and 16 females) were analyzed. The oldest was 78 years old and the youngest was 24 years old, with an average of 42.16 years. Of these, 19 were located in the skull, 2 in the cervical spine, 1 in the lumbar spine, and 9 in the sacrococcygeal vertebrae. 29 routine CT examination, 29 routine MRI examination, CT and MRI at the same time check 27 cases. Results: CT and MRI showed soft tissue mass in 31 cases, bone destruction in 29 cases (93.55%) and calcification in 16 cases (51.61%). Tumor morphology was irregular, round. Enhanced scan Most lesions showed mild enhancement. 29% of the group occurred in the sacrococcygeal. Conclusion: The typical manifestations of chordoma are soft tissue mass of the slope or sacrococcygeal with destruction of bone mass and intralesional calcification. CT and MRI examination of chordoma diagnosis and extent of tumor invasion is very helpful.
