眼眶血管性肿瘤和畸形的超声及CT诊断

Diagnosis by ultrasonography and CT scan in orbital vascular tumors and malformations

目的 探讨眼眶血管性肿瘤和畸形的超声 (标准化A/B超 )及CT检查诊断价值。方法收集 10 8例眼眶血管性病变患者的临床资料和超声 (98例 )及CT扫描 (10 8例 )图像进行回顾性分析 ,其中 94例经手术及病理证实。海绵状血管瘤 5 4例 ,静脉曲张 2 6例 ,静脉性血管瘤 13例 ,婴儿型血管瘤 5例 ,淋巴管瘤 6例 ,其他肿瘤 4例。结果 超声检查肿瘤显示率达 98% (96 /98) ,假阴性率 2 % (2 /98) ,术前定性确诊率为 93% (91/98)。CT扫描的肿瘤显示率达 10 0 % (10 8/10 8) ,术前定性确诊率为92 % (99/10 8)。结论 眼眶血管性肿瘤和畸形的超声检查与CT扫描联合应用对判断病变的性质、范围、位置及手术入路的选择至关重要。

Objective To analyze the value of ultrasonography (standardized A/B scan) and CT scan in the diagnosis of orbital vascular tumors and vascular malformations. Methods One hundred and eight cases of orbital vascular tumors and malformations were studied, including 98 cases examined by ultrasonography, 108 cases examined by CT scan and 94 cases studied by orbital operation and pathological examination. There were 54 cases of cavernous hemangioma, 26 cases of varix, 13 cases of venous hemangioma, 6 cases of lymphangioma, 5 cases of infantile hemangioma and 4 cases of others disorders. Results The tumor could be detected in ultrasonography in 96/98 cases (98%), the false negative rate of ultrasonography was 2% (2/98). The nature of the tumor could be determined by ultrasonography in 93%(91/98) cases pre-operatively. The tumor could be found by CT in all cases (108/108). The nature of the tumor could be determined by CT in 92%(99/108) cases pre-operatively. Conclusions Combined ultrasonography with CT scan can estimate the nature, extent and location of orbital vascular tumors and malformations and can be useful for selection of the route of orbital operation.
