目的总结海绵窦病变的种类、MR I诊断及鉴别诊断。方法分析69例经临床或病理证实的海绵窦病变MR I资料。结果69例海绵窦病变可大致分为四大类:炎性病变14例(细菌性炎症6例、非细菌性炎症8例)、血管性病变13例(颈内动脉瘤6例、海绵状血管瘤5例、颈内动脉海绵窦瘘2例)、原发性肿瘤13例(脑膜瘤7例、神经源性肿瘤5例、胆脂瘤1例)和继发性肿瘤29例(邻近组织器官肿瘤的直接侵犯27例、转移瘤2例)。结论海绵窦病变MR I表现各具形态及信号特点。MR I对各类海绵窦病变的诊断和鉴别诊断具有重要价值。
Objective To summarize the types of cavernous sinus lesions, MR I diagnosis and differential diagnosis. Methods MR Ⅰ data of 69 cases with pathologically confirmed cavernous sinus lesions were analyzed. Results 69 cases of cavernous sinus lesions can be divided into four broad categories: inflammatory lesions in 14 cases (bacterial inflammation in 6 cases, non-bacterial inflammation in 8 cases), vascular lesions in 13 cases (6 cases of internal carotid aneurysm, cavernous 5 cases of tumor, 2 cases of internal carotid cavernous fistula), 13 cases of primary tumor (7 cases of meningioma, 5 cases of neurogenic tumor, 1 case of cholesteatoma) and 29 cases of secondary tumor (adjacent tissues and organs 27 cases of direct tumor invasion, 2 cases of metastases). Conclusion Cavernous sinus lesions MR I performance of each shape and signal characteristics. MR I of various types of cavernous sinus disease diagnosis and differential diagnosis of great value.
