鼻咽腺样体肥大的CT诊断

目的:探讨鼻咽腺样体肥大的CT表现及其鉴别诊断。方法:分析30例鼻咽腺样体肥大的CT表现,重点观察病变部位、咽旁软组织间隙、副鼻窦及乳突改变。结果:鼻咽顶壁和后壁软组织增厚,弥漫性向前下突出22例,呈山丘样突出8例,伴有双侧咽鼓管口淋巴组织增生及副鼻窦炎9例,伴中耳乳突炎5例,伴面骨发育障碍牙列不齐,堵塞后鼻孔2例。结论:鼻咽腺样体肥大不累及咽缝,无咽旁间隙侵犯。

CT Diagnosis of Nasopharyngeal Adenoid Hypertrophy

Objective:To discuss CT features and differentiation of the nasopharyngeal adenoid hypertrophy.Methods:CT findings of 30 patients with nasopharyngeal adenoid hypertrophy were retrospectively analyzed.We focused on the (lesion's) site,parapharyngeal soft tissue space and the changes of paranasal sinuses and mastoid process.Results:There was thickening of the superior and posterior pharyngeal wall,with diffuse protruding forward and downward in 22 cases.In 8 (cases) there was a protruding like a hill.There was also lymph tissue hyperplasia of bilateral pharyngeal opening of audirory tube and paranasal sinuses inflammation in 9 cases.In 5 cases there was inflammation of middle ear or mastoid process,and in 2 cases there was malformation of the facial bone with disarrangement of the teeth and obstruction of the choanae.(Conclusion:)Nasoharyngeal adenoid huypertrophy did not involve pharyngeal slot and parapharyngeal space.
