CT动态增强扫描在眼眶海绵状血管瘤诊断中的价值

Application of enhanced dynamic CT scanning in diagnosis of orbital cavernous hemangioma

目的:研究眼眶海绵状血管瘤的CT表现,特别是CT动态增强扫描在海绵状血管瘤诊断和鉴别诊断中的价值。方法:经手术病理证实的海绵状血管瘤12例,常规行CT平扫和动态增强扫描。结果:12例肿瘤中10例显示不均匀渐进性强化,2例肿瘤直径小于1.5cm,显示均匀强化。结论:渐进性强化是眼眶海绵状血管瘤的特点,CT动态增强扫描有助于诊断海绵状血管瘤。

To explore application of enhanced dynamic CT scanning in diagnosis of orbital cavernous hemangioma. Methods. A total of 12 cases with confirmed orbital cavernous hemangioma by surgerical pathological analysis were selected. All had conventional CT scanning and enhanced dynamic CT. Results. The result of enhanced dynamic CT showed progressive enhancement in 10 cases and homogeneous enhancement in 2 cases, who had tumor of diameter less than 1.5 cm. Oonclusions. Enhanced dynamic CT is helpful in diagnosis of cavernous hemangioma, which is characterized as progressive enhancement.
