摘　　要：目的探讨眶内海绵状血管瘤的MRI表现。方法眶内海绵状血管瘤16例，男7例，女9例，年龄4。74岁，使用1．5T超导MPd，常规SE／VE序列，T1WI、T2WI，均注射Gd-DTPA。结果MRI平扫表现：4例长T1长T2信号，8例等T1长T2信号，3例短T1长T2信号（压脂），1例等T1等T2信号；其中2例肿瘤内可见血管流空影。增强表现：7例呈明显均匀强化，5例呈中度略不均匀强化，4例分别为轻度强化、边缘强化及结节强化。结论根据MRI眶内海绵状血管瘤的形态、信号、强化表现及好发年龄等特点综合分析可以做出定性诊断。Objective To evaluate the MRI diagnosis of intraorbital cavernous hemangioma and to discuss the differential diagnosis, Methods Studies were conducted in 16 patients （ 7 males, 9 females, 4 - 74 years of age） with clinically and pathological proved infraorbital cavernous hemangioma. MRI studies were performed on 1.5 T MR scanner. SE/VE,. T1WI and T2 WI were acquired in all patients. All patients were injected with contrast Gd- DTPA. Results The tumors showed signals of long Tland long T2 in 4 cases, equal T1 and long T2 in 8 cases, short T1 and long T2（fat suppression ） in 3 cases, equal T1 and equal T2 in 1 case;flow empty in 2 cases;obvious even enhaacement in 7 cases,moderatel slight uneven enhaacement in 5 cases, and slight, marginal, multi- mode enhancement in 4 cases.Conclusions According to the MPd feature and comprehensive analysis, the qualitative diagnosis of intraorbital carvemous hemangioma can be made by MR imaging.
