| 中文摘要: |
| 目的 探讨鼻腔鼻窦横纹肌肉瘤(RMS)的CT表现。方法 回顾性分析经病理学证实的鼻腔鼻窦RMS 18例,均行横断面及冠状面CT扫描,其中15例行增强扫描。结果 主要临床表现为鼻堵及眼突。最常见部位为上颌窦。HRCT均表现为鼻腔及鼻窦内大的软组织肿块影,密度不均。3例伴有钙化。18例窦壁骨质破坏。12例肿瘤侵犯鼻窦周围脂肪间隙及邻近结构。病灶强化不均匀。结论 CT扫描能清晰显示病灶及其侵犯程度,对指导临床手术及其他治疗方法具有重要的意义。 |

| Objective To investigate the imaging findings of rhabdomyosarcoma (RMS) of nose and paranasal sinus. Methods High resolution CT (HRCT) findings of 18 patients with rhabdomyosarcoma of nose and nasal sinus confirmed by pathology were retrospectively analyzed.Axial and coronal CT scannings were performed in all cases,in which contrast scanning was performed in 15 cases. Results The commonest clinical manifestation was nasal obstruction and exophthalmos.On HRCT,heterogeneous soft tissue mass was found in nasal cavity and paranasal sinus.Calcification was demonstrated in 3 cases,bony destruction in 18 cases,and invasion of adjacent structures in 12 cases.Heterogeneous enhancement was found in 15 cases. Conclusion HRCT can clearly demonstrate the shape,features,and extent of RMS which can contribute to choosing clinical surgery and other therapy modalities. |
