摘　　要：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。Objective To study the x-ray and CT findings of mucoceles of frontal and ethmoid sinuses and their value of diagnosis. Methods Twelve cases including fifteen mucoceles were studied. X-ray film and CT were performed in all cases .X-ray and CT findings were analyzed and correlated with operative findings. Results Of 15 mucoceles, 9 were found in ethmoid sinuses, 6 in frontal sinuses. Density of sinuses cavity increase in all cases .Sinus expansion, thinning of sinus wall and bony defect were found on X-ray film .CT showed low density with respect to muscle in 11 sinuses, identical in 3 and high density in one case and periphral sinus mucoca enhencement in 3 cases .Sinus expansion and thinning of the sinus wall were found in all cases, the configuration of mucoceles is smooth and clear.Bony defect is obvious in 9 mucoceles and mucoceles invade into adjacent consturctions. Conclusions CT can accuratelly display the bony change and characteristic findings of mucocele and play an important role in diagnosis and differential diagnosis
