摘要
目的:总结海绵窦病变的种类、MRI诊断及鉴别诊断。方法:分析98例经临床或病理证实的海绵窦病变MRI资料。结果:98例海绵窦病变可大致分为四大类:炎性病变16例、血管性病变14例、原发性肿瘤13例和继发性肿瘤55例。炎性病变以双侧或单侧海绵窦软组织影增厚并向眶尖、眶上裂及颅底蔓延为主要MRI表现;血管性病变中颈内动脉瘤及颈内动脉海绵窦瘘以海绵窦异常流空信号及相应MRA改变为特征,而海绵状血管瘤的表现则类似肿瘤性病变;原发或继发性肿瘤主要表现为海绵窦区不同形态和信号肿块及邻近结构受累改变。结论:海绵窦病变MRI表现各具形态及信号特点。MRI对各类海绵窦病变的诊断和鉴别诊断具有极其重要价值。
Objective To sum up the types, MRI findings and diagnosis of the cavernous sinus diseases. Methods MRI images of 98 patients with the cavernous sinus diseases proved by clinic or pathology were retrospectively reviewed. Results Ninty-eight cases of cavernous sinus diseases were classified into four types based on etiologies, inflammatory lesions （16 cases）, angio-diseases （14cases ）,l^rlmarv tumors （13 cases）,and secondary tumors （55 cases）. The cavernous sinus patch or nodule abnormal chickening and abnormal signals extending towards fissure orbitalis superior and skull base were found in inflammatory lesions in MRI. The flow void-sign and abnormalities of MRA were the main features of the internal carotiol artery aneurysm and ICA-cavernous sinus fistula. The MRI manifestations of the cavernous sinus cavernous hemagioma were similar to some tumors. Single or multiple masses were showed in the cavernous sinus primary or secondary tumors cases. Conclusion There are different MRI features in shape and signal of lesions in the different cavernous sinus diseases. MRI plays an extremely important role in diagnosis and differential diagnosis of the cavernous sinus diseases.
