摘　　要：目的　评价MRI对鼻咽潴留囊肿的诊断价值。方法　回顾性分析 8例经手术穿刺及病理证实的鼻咽潴留囊肿的MRI表现。结果　MRI表现为 :8例鼻咽潴留囊肿呈圆形 ,边界清晰 ,T1WI上 6例呈低信号 ,2例呈稍低信号 ,T2 WI均呈高信号。结论　MRI对鼻咽潴留囊肿的诊断具有较高的敏感性和特异性。是诊断鼻咽潴留囊肿的重要方法。Objective To evaluate the value of MRI in the diagnosis of nasopharynx retention cyst. Methods The appearances of nasopharynx retention cyst in 8 cases were retrospectively analyzed on MRI. All cases were confirmed by surgical and pathological findings. Results The MRI appearances of 8 cases were as follows: 8 cases of the cysts appeared as round in shape with defined margin. On T 1 weighted images, the lesion appeared as hypointense (6/8) and slight hypointense (2/8). On T 2 weighted images, all of the lesions appeared as hyperintense. Conclusion MRI possessed a high sensitivity and specificity, and was an important method on the diagnosis of nasopharynx retention cyst.
