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 the value of CT in the diagnosis of pheochromocytoma. Methods 43 cases (benign 40 cases, malignant 3 cases) pathologically confirmed pheochromocytoma CT signs and B-ultrasound results. Results There were 34 adrenal tumors and 9 ectopic tumors (21%). CT findings: 81% (35/43) tumor diameter greater than 3cm. Tumors were significantly enhanced, 32 cases (74.4%) of uneven density, often accompanied by necrosis, liquefaction, cystic change or calcification. Clear boundaries of benign lesions, malignant lesions easily infringe the adjacent tissue. The CT localization rate was 93.3% and the qualitative rate was 88.4% higher than that of B ultrasound (P <0.05). Conclusion CT has a high value for the localization and qualitative diagnosis of pheochromocytoma and is the main imaging method.
