目的是研究额、筛窦粘液囊肿Ｘ线和ＣＴ表现，并探讨其在诊断鼻窦粘液囊肿方面的价值。方法粘液囊肿患者１２例，共１５个粘液囊肿，所有患者都行Ｘ线平片检查和ＣＴ检查，结合手术对照分析额、筛窦粘液囊肿的Ｘ线和ＣＴ表现。结果 ９个粘液囊肿发生于筛窦， ６个粘液囊肿发生于额窦。 Ｘ线表现： １５ 个粘液囊肿都表现为窦腔透亮度的减低，不同程度的窦腔扩大，骨质变薄及窦壁骨质的吸收、破坏。ＣＴ表现：１１个粘液囊肿表现为低密度，３个表现为等密度，１个表现为高密度（同面部肌肉密度相比）。４例行ＣＴ增强扫描，３例显示囊肿周边粘膜环行强化而中央无强化。１５个粘液囊肿均表现为不同程度的窦腔膨大、骨质变薄，囊肿轮廓光滑完整，其中９个粘液囊肿可清晰显示骨质的吸收、破坏，囊肿突入到邻近结构。结论是ＣＴ检查能准确、全面显示鼻窦粘液囊肿的骨质改变，又能显示其特征性影像表现，对于粘液囊肿的诊断和鉴别有重要意义。
The purpose of this study was to evaluate the X-ray and CT findings of the frontal and ethmoid sinus mucus cysts and to explore its value in the diagnosis of sinonasal cyst. Methods Twelve patients with mucinous cyst were included in this study. Fifteen mucoceles were obtained. All patients underwent X-ray and CT examinations. X-ray and CT findings of the frontal and ethmoid mucoceles were analyzed with surgical control. Results Nine mucinous cysts occurred in the ethmoid sinus and six mucinous cysts occurred in the frontal sinus. X-ray manifestations: 15 mucus cysts showed a decrease in the sinus cavity brightness, varying degrees of sinus enlargement, thinning of the bone and sinus wall bone absorption, destruction. CT manifestations: 11 mucous cysts showed low density, three showed equal density, one showed high density (compared with the facial muscle density). 4 cases of CT enhanced scanning, 3 cases showed cyst mucosa around the Central enhanced and no central enhancement. 15 mucous cysts showed varying degrees of sinus enlargement, bone thinning, cyst outline smooth and complete, of which 9 mucus cysts can clearly show the bone absorption, destruction, cyst into the adjacent structures. The conclusion is that CT examination can accurately and completely show the bone changes of the sinus mucocele, and can also show its characteristic imaging performance, for the diagnosis and identification of mucus cysts is of great significance.
