To examine the diagnostic value of imaging features in cavernous sinus hemangioma (CSH).
The clinical and imaging data of patients with pathologically confirmed CSH, cavernous sinus meningioma, trigeminal schwannoma and pituitary adenoma invading the cavernous sinus between May 2017 and May 2022 were retrospectively analyzed. The cases were divided into the CSH and non-CSH groups to summarize the magnetic resonance imaging (MRI) characteristics of CSH. Univariate χ2 analysis was performed to assess five indexes, including signal intensity on T2WI, homogeneity of T2WI, enhancement of enhanced T1, enhanced T1 with dural tail sign, and cavernous sinus swelling and extrusion sign.
There were significant differences in four features, including hyperintensity on T2WI, homogeneity of T2WI, T1-enhanced without meningeal tail sign, and cavernous sinus swelling and extrusion sign between the CSH and non-CSH groups, with cavernous sinus swelling and extrusion sign showing the most pronounced distinction, with a sensitivity of 100%, a specificity of 93.02%, and an accuracy of 94.23%. The four features could be jointly used as diagnostic criteria, with a sensitivity of 94.44%, a specificity of 100.00%, and an accuracy of 99.04%.
Cavernous sinus swelling and extrusion sign is a reliable imaging index for CSH diagnosis. Homogenous hyperintensity or marked hyperintensity on T2WI, enhanced T1 without dural tail sign, and cavernous sinus swelling and extrusion sign could be jointly used as diagnostic criteria, which may improve the accuracy of CSH diagnosis.
探讨影像学特征在海绵窦血管瘤（CSH）中的诊断价值。
回顾性分析2017年5月至2022年5月间病理确诊的CSH、海绵窦脑膜瘤、三叉神经鞘瘤及侵犯海绵窦的垂体腺瘤患者的临床及影像学资料。将病例分为CSH组和非CSH组，总结CSH的磁共振成像（MRI）特征。采用单因素χ2分析评估5项指标，包括T2加权像（T2WI）信号强度、T2WI均匀性、增强T1加权像（T1WI）强化情况、有硬膜尾征的增强T1WI以及海绵窦肿胀和挤压征。
CSH组与非CSH组在T2WI高信号、T2WI均匀性、无脑膜尾征的T1WI强化以及海绵窦肿胀和挤压征这4项特征上存在显著差异，其中海绵窦肿胀和挤压征差异最为明显，敏感性为100%，特异性为93.02%，准确性为94.23%。这4项特征可联合用作诊断标准，敏感性为94.44%，特异性为100.00%，准确性为99.04%。
海绵窦肿胀和挤压征是CSH诊断的可靠影像学指标。T2WI上均匀高信号或明显高信号、无硬膜尾征的增强T1WI以及海绵窦肿胀和挤压征可联合用作诊断标准，这可能提高CSH诊断的准确性。
