摘要
目的 :探讨CT对嗜铬细胞瘤定位与定性的诊断价值。方法 :回顾性分析了CT检查后经手术病理证实并有完整病史资料的患者 4 2例。结果 :起源于肾上腺者 35例 (双侧 5例 ) ,异位 7例 ,其中恶性 6例 ,儿童 4例。嗜铬细胞瘤的CT表现为肿块较大、密度均匀或不均匀的特点 ,可伴有囊变、坏死或出血 ,增强后肿瘤实质明显强化 ,而坏死、囊变区无强化或略有强化。CT对该病定位率 95 .2 % ,定性率 90 .5 %。结论 :CT是嗜铬细胞瘤定位和定性诊断最有效的影像学方法 ,并能对多发。
Objective: To investigate the CT diagnostic value in the localization and qualitation of pheochromocytoma. Methods: Forty two cases of pheochromocytoma examined by CT with complete clinical information and surgical pathologic results were retrospectively analysed. Results: Adrenal masses were found in 35 cases(bilateral in 5 cases)and ectopic masses in 7 cases. Of all the cases 6 were malignant and 4 were found in children. CT findings are of characteristic features: Usually, pheochromocytomas were large in size and homogeneous or inhomogeneous in density, central cystic changes, necrosis and hemorrhage may be seen; tumors were markedly enhanced after contrast administration. The accuracy ratio of CT diagnosis was 95.2% in locating tumors and 90.5% in qualitative analysis. Conclusion: At present, CT is the most effective imaging modality in the localization of pheochromocyoma and determination of the pathologic nature.
