目的探讨颅咽管瘤的MRI影像学表现,评价其诊断价值。方法回顾性分析59例经手术病理证实的颅咽管瘤的MRI表现。结果59例颅咽管瘤患者,40例(67.8%)病灶位于鞍上,16例(27.1%)位于鞍内,3例(5.1%)位于鞍旁,视神经受压、变形、移位51例,垂体正常显示32例,垂体受压变小15例,垂体未显示12例。肿瘤的信号在T2WI上多呈混杂高信号,而T1WI上可有高、等、低等多种表现。结论MRI可清楚显示鞍区肿瘤与周围结构,其多信号变化反映了肿瘤囊液成分的不同,MRI是诊断颅咽管瘤的有效方法。
Objective To investigate the MRI findings of craniopharyngioma and evaluate its diagnostic value. Methods The MRI findings of 59 cases of craniopharyngioma confirmed by surgery and pathology were retrospectively analyzed. Results In 59 cases of craniopharyngioma, 40 cases (67.8%) were located in the saddle, 16 cases (27.1%) were located in the saddle, 3 cases (5.1%) were located in the parasella, the optic nerve was compressed, deformed and displaced , Pituitary normal display 32 cases, pituitary compression smaller 15 cases, pituitary did not show 12 cases. Tumor signals are mostly mixed high signal on T2WI, while T1WI may have high, low, and many other performance. Conclusion MRI can clearly show the structure of the sella region and the surrounding area. The multi-signal changes reflect the different components of the tumor cyst fluid. MRI is an effective method for the diagnosis of craniopharyngioma.
