Computed Tomography Features of Inflammatory Myofibroblastic Tumor

More Information
  • 摘要:   目的  探讨炎性肌纤维母细胞瘤的计算机断层摄影(computed tomography, CT)表现, 以提高对该病CT表现的认识。  方法  选择本院9例经病理证实的炎性肌纤维母细胞瘤患者, 回顾性分析其CT平扫及增强表现。  结果  CT示肺内肌纤维母细胞瘤3例, 2例表现为界限清楚的肿块, 1例仅表现为支气管阻塞, 未见肿块; 纵隔肌纤维母细胞瘤3例, CT均表现为软组织密度肿块, 1例界限清楚, 2例与周围结构分界不清; 鼻根部、颈部及盆腔肌纤维母细胞瘤各1例, 表现为囊实性或实性肿块, 部分病变界限不清, 侵犯周围组织; 3例病变增强扫描后呈明显不均匀强化。  结论  炎性肌纤维母细胞瘤CT表现具有一定的特点, 但最终确诊仍需依靠病理学。
  • 图  1  肺内炎性肌纤维母细胞瘤CT表现

    A. CT增强示右肺中叶界限清楚的肿块(黑箭头),大小8. 4 cm × 7. 4 cm × 7. 0 cm,明显不均匀强化,并可见右肺中叶支气管闭塞(白箭)及远端肺不张(白星); B. 7个月后复查,CT增强示肝表面转移灶,呈软组织团块,明显不均匀强化(黑箭头)

    图  2  纵隔炎性肌纤维母细胞瘤CT表现

    A. CT平扫示升主动脉、上腔静脉、肺动脉间软组织密度占位(白箭头),密度均匀,界限清楚; B. CT病变增强后上述病变明显强化,内部无明显强化低密度区(黑箭头)

    图  3  鼻根部炎性肌纤维母细胞瘤CT表现

    A.软组织窗右侧鼻根部实性占位(黑箭头),呈软组织密度,部分突入右眼眶; B.骨窗示邻近筛窦骨质破坏显示清晰(白弯箭头); C.冠状位显示病变侵入右侧眼眶更加清楚(白箭),左侧上颌窦黏膜增厚

    图  4  盆腔炎性肌纤维母细胞瘤CT表现

    A. CT平扫示盆腔左侧圆形囊实性病灶(白箭),内部密度不均,囊壁内缘欠光滑; B. CT增强示病变内分隔,囊壁及分隔明显强化,内部液性密度未见强化,病变周围脂肪间隙模糊,与周围肠道分界欠清(黑箭头)
