目的 探讨颅咽管瘤的影像学表现及其诊断价值,提高影像诊断率。方法 利用CT和MRI检查方法,分析了9例经手术病理证实为颅咽管瘤的影像学表现,讨论了颅咽管瘤的病理及分型,临床及预后,CT和MRI对本病的诊断及鉴别诊断。结果 囊性者6例,CT为边清低密度影,伴钙化,呈环形或岛状强化。实性者1例,为混杂密度影。囊实混合者2例。MRI见 T_1WI呈低、等或高信号,T_2WI呈混杂高信号。结论 CT及MRI对颅咽管瘤的定位诊断率达100％,定性诊断率89％,为临床准确提供手术方式。
Objective To explore the imaging features and diagnostic value of craniopharyngiomas and to improve the diagnostic rate of the images. Methods CT and MRI were used to analyze the imaging findings of 9 cases of craniopharyngioma confirmed by surgery and pathology. The pathology, classification, clinical and prognosis of craniopharyngioma were discussed. The diagnosis of this disease was analyzed by CT and MRI And differential diagnosis. Results 6 cases of cystic, CT-side low density shadow, with calcification, showed ring or island-like enhancement. 1 cases of solid, mixed density shadow. Capsule mix in 2 cases. MRI see T_1WI was low, or high signal, T_2WI was mixed high signal. Conclusion The localization of CT and MRI in the diagnosis of craniopharyngioma is 100%, and the diagnostic rate is 89%. It provides a surgical method for clinical diagnosis.
