【摘要】：目的分析鞍区囊性病变的CT、MRI影像特征。方法回顾性分析83例鞍区囊性病变患者的临床和影像学资料,观察囊性病灶的位置、大小、囊的数目、囊壁厚度及壁结节、海绵窦包绕等特殊征象。结果 83例中,囊性垂体瘤33例、囊性颅咽管瘤28例、Rathke囊肿15例、皮样囊肿2例、表皮样囊肿2例、蛛网膜囊肿2例、垂体脓肿1例。囊性垂体瘤、蛛网膜囊肿主要表现为T1WI低信号,T2WI高信号;囊性颅咽管瘤及Rathke囊肿信号表现复杂;皮样囊肿、表皮样囊肿及垂体脓肿DWI呈高信号。3种常见鞍区囊性病变(囊性垂体瘤、囊性颅咽管瘤、Rathke囊肿)间囊的大小、数量及囊壁厚度差异均有统计学意义(P均0.05)。结论根据囊性病变的位置、形态、信号特征、囊的特点及一些特殊征象,可提高对鞍区囊性病变的鉴别诊断能力。
[Abstract]:Objective to analyze the CT MRI features of Sellar cystic lesions.Methods the clinical and imaging data of 83 patients with Sellar region cystic lesions were retrospectively analyzed. The location, size, number, thickness and wall nodules of cystic lesions, cavernous sinus wrapping and other special signs were observed.Results of the 83 cases, 33 were cystic pituitary adenoma, 15 were cystic craniopharyngioma, 15 were dermoid cysts, 2 were epidermoid cysts, 2 were arachnoid cysts and 1 was pituitary abscess.Cystic pituitary adenomas, arachnoid cysts with high signal intensity on T1WI hypointensity T2WI, complex signal intensity in cystic craniopharyngioma and Rathke cysts, dermoid cysts,The DWI of epidermoid cyst and pituitary abscess showed high signal intensity. 3 kinds of common Sellar cystic lesions (cystic pituitary adenoma, cystic craniopharyngioma rathke's cyst) had significant difference in size, quantity and thickness of cyst wall (P < 0.05).Conclusion according to the location, morphology, signal characteristics, cystic features and some special signs of cystic lesions, the differential diagnosis of Sellar region cystic lesions can be improved.
