摘要
目的 评估CT对嗜铬细胞瘤的诊断价值。方法 分析43例(良性40例,恶性3例)经病理证实的嗜铬细胞瘤CT征象并与B超结果对照。结果 肾上腺区肿瘤34例,异位瘤9例(21％)。CT表现:81％(35/43)肿块直径大于3cm。肿瘤实质均显著强化,32例(74.4％)密度不均匀,常伴有坏死、液化、囊变或钙化。良性病变边界清晰,恶性病变易侵犯邻近组织。CT定位率为93.3％、定性率为88.4％均高于B超(P<0.05)。结论 CT对嗜铬细胞瘤的定位、定性诊断具有较高价值,是主要的影像检查方法。
Objective To evaluate CT diagnosis in pheochromocytoma. Methods The CTmanifestations of 43 cases (benign 40, malignant 3) proved pathologically were analyzed retrospectively, and compared with their B mode ultrasound results. Results 43 pheochromocytomas included 34 adrenal masses and 9 ectopic masses (21%). The CT appearances were: The diameter of masses in 81% (35/43) cases was larger than 3cm, all masses were markedly enhanced after bolus injection of contrast media. 32/43(74. 4% ) of cases were revealed heterogeneous, commonly showing necrosis, liquefaction, cystis or calciri cation. Benign lesions showed distinct margin, Malignant lesions ususally invased into the nearby structures, The accuracy rate of CT diagnosis in localization and qualitation was 93. 3% and 88. 4% respectively, and it was higher than that of sonography (P <0. 05). Conclusion CT has important value and is more effective imaging modality in local - ization and determination of pheochromocytoma.
