摘要
目的：提高对鼻前庭囊肿CT表现的认识。方法：回顾性分析47例经病理证实的鼻前庭囊肿的临床、病理及CT表现。结果：47例均为单侧发生,其中右侧27例,左侧20例。39例病变呈圆形或类圆形,8例为不规则形。大部分病变边界清晰、边缘光整,密度均匀,CT值15～65 Hu。增强CT囊肿无明显强化,合并感染时囊壁环形强化。33例可见邻近骨质受压呈弧形改变。结论：鼻前庭囊肿CT表现有一定特征,病变多为圆形、类圆形,边缘光整,密度均匀,邻近骨质弧形改变是其常见表现。
Purpose： To improve diagnostic capabilities of CT about nasal vestibule cyst. Methods： Clinical and CT images of 47 cases of nasal vestibule cyst confirmed by pathology were retrospectively analyzed. Results： 47 cases were unilateral, of which 27 cases in the right side, 20 in left side. 39 cases of lesions were round or oval, eight cases irregular shape. Clear boundary, edge finishing, uniform density were seen in most lesions with CT value range from 15 Hu to 65 Hu. There are no enhancements in major cyst, except cyst wall ring enhancement in those with infection. 33 cases have curved visible change in adjacent bone. Conclusion： There are some characteristic CT manifestations of nasal vestibule cyst, lesions were round or oval, with edge finishing and uniform density, curved change of adjacent bone is usually seen.
