眼眶内海绵状血管瘤的螺旋CT表现与病理的关系

SPIRAL CT MANIFESTATIONS AND PATHOLOGICAL CHARACTERISTIICS OF ORBITAL CAVERNOUS HEMANGIMA

目的分析眼眶海绵状血管瘤的CT表现及其病理特征，以提高其诊断准确性。方法回顾性分析36例经手术病理证实的眼眶内海绵状血管癌或肿瘤样病变的MSCT表现，并与手术所见和病理结果进行对照。结果36例眼眶海绵状血管瘤边缘规则光整，肿瘤直径0．7～3．2cm，平均2．3cm。所有肿瘤呈进行性延迟强化，其中8例肿瘤强化显著，5例中等程度强化。CT对病变与周围结构的关系诊断较准确，并且能对病灶做出定性诊断。结论CT可以很好地显示眼眶海绵状血管瘤及其与周围解剖结构的关系，在病变的定性方面也有一定的价值，能为临床治疗方案的选择提供可靠的信息。

Objective To analyze the CT manifestations and pathological characteristics of orbital cavernous hemangioma so as to make accurate diagnoses. Methods The spiral CT manifestations of 36 cases of tumor of duodenum were analyzed retrospectively and them contrasted with the pathological results. Results The tumors with smooth and regular margins in 36 cases all showed progressively delayed potentialization. The diameters ranged from 0.7cm to 3.2cm with the average being 2.3cm. 8 cases showed marked potentialization and 5 cases showed moderate one. Conclusion Spiral CT can be used to accurately examine orbital cavernous hemangioma and qualitatively determine the lesions so as to provide reliable information for different therapies.
