目的 观察MRI影像学检查在海绵 窦海绵状血管瘤中的临床特征。方法 收 集7例海绵窦海绵状血管瘤患者的临床资 料，回归性分析患者海绵窦区的病灶大 小、形态；MR T1WI、T2WI、DWI的信号特 征；误诊与确诊情况。结果 7例均属海绵 窦单发病灶，4例为左侧，3例为右侧；最 大径线2.5-6.1cm，平均3.9cm；7例中有6 例呈横向生长，病灶均为左右走向，范围 多横跨脑蝶鞍内外，呈现哑铃状或葫芦的 高信号影。在MRI影像学图像中，7例病变 的T1WI序列信号均显著小于脑白质，稍低 于脑灰质；4例患者的T1WI散在分布高信 号影，并且T2WI序列整体的高信号显著高 于脑实质信号；增强扫描后，7例病灶均 显著均匀强化，其中2例病灶出现边缘脑 膜尾征；1例患者的T1WI、T2WI、DWI上均 呈高低混杂信号，增强扫描后边缘部分片 状强化。7例患者有2例误诊为脑膜瘤，术 后病理检查实为CSHAs，误诊时间分别为3 周、5周。结论 海绵窦海绵状血管瘤MRI 平扫与增强扫描具有一定的特征性，结合 影像结果有助于提高临床结果的准确性。

Objective To observe the clinical features of MRI imaging examination in cavernous sinus cavernous hemangioma. Methods The clinical data of 7 cases of patients with cavernous sinus cavernous hemangioma was collected, and the size and shape of lesions in cavernous sinus area, the signal features of MR, T1WI, T2WI and DWI, misdiagnosis and diagnosis were analyzed retrospectively. Results 7 cases were cavernous sinus single lesion, 4 cases in left side, 3 cases in right side, maximum diameter was 2.5- 6.1cm, average was 3.9cm. There were 6 cases in 7 cases showed lateral growth, lesions were all in left and right direction, which were about to range across internal and external sella turcica with dumbbell-shaped and gourd-shaped high signal shadow.In MRI images, the T1WI sequence signal of 7 lesions was apparently smaller than that of alba, but slightly lower than that of ectocinerea. 4 cases of patients with T1WI scattered in the high signal shadow, the overall high signal of T2WI sequence was significantly higher than that of brain parenchyma signal, after enhanced scan, 7 lesions were evidently and evenly enhanced, including 2 cases of marginal dural tail sign, and 1 case showed high-low mixed signal in T1WI, T2WI and DWI, and marginal plate reinforcement was emerged after enhanced scan. In 7 cases of patients, 2 cases were misdiagnosed as meningioma while the postoperative pathological examination was CSHAs. The time of misdiagnosis was 3 weeks and 5 weeks respectively. Conclusion MRI scan and enhanced scan of cavernous sinus cavernous hemangioma have certain characteristics each, and the combination with imaging results is helpful for improvement of clinical outcomes accuracy.
