肾上腺转移瘤的螺旋CT诊断

目的探讨肾上腺转移瘤的螺旋CT特征及CT在肾上腺转移瘤诊断中的应用价值。方法对42例患者行螺旋CT扫描,其中37例行增强扫描。结果单侧肾上腺肿块28例(67%),双侧22例(33%)。肿块直径大小1.5～12cm,分别呈圆形、卵圆形和分叶状不规则形。密度为实性、囊性或囊实性,增强后实性肿块及囊壁有强化。结论螺旋CT是发现肾上腺肿瘤可靠、有效的检查方法。肾上腺转移瘤的诊断是综合性的,包括原发癌史、恶性征等。肾上腺肿块的恶性征为肿块直径>5cm,常呈分叶或不规则外形,密度不均。

Spiral CT diagnosis of adrenal metastasis tumor

Objective To discuss the characteristics of spiral CT and its value in diagnosis of adrenal metastasis tumor. Methods Forty-two patients were detected with CT scan and among them 37 cases were performed enhanced CT scan. Results The unilateral tumor were 28/42 and bilateral tumor were 22/42 cases with diameter ranged from 1.5-12 cm in round, oval, lobular and irregular in shape. The tumor density was parenchyma or cystic and both of the parenchyma and wall of cyst were enhanced after detection. Conclusion Spiral CT might be a reliable andeffective method to detect the adrenal metastasis tumor. The diagnosis of this tumor is complicated with primary tumor history and malignantsigns. The malignant sign should be the tumor is more than 5 cm in diameter and lobular or irregular with un-even desity.
