目的探讨肾嫌色细胞癌的CT表现,以提高对该病的认识。方法 10例病理证实的肾嫌色细胞癌患者,行CT平扫及增强检查,回顾性分析其CT表现。结果 10例嫌色细胞癌均为单侧单发病灶。肿瘤最大径范围2.5～6.9cm,平均4.65 cm。8例肿瘤平扫密度表现为略高密度或等密度,2例呈混杂密度。9例病灶增强后与周围肾实质分界清晰。9例呈外凸性生长。6例肿瘤形态上呈圆形或类圆形,4例形态欠规则,其中3例表现为特征性的“8”字征或沙漏征。肿瘤呈轻中度强化,强化方式均匀或不均匀,1例内部可见轮辐样强化。所有肿瘤均无肾周浸润、肾盂受侵、淋巴结肿大、肾静脉受累表现。结论肾嫌色细胞癌的CT表现具有一定的特点,最终仍需要病理学确诊。 Objective To investigate the CT manifestations of chromophobe renal cell carcinoma in order to improve the understanding of the disease. Methods Ten patients with renal cell carcinoma of renal cell carcinoma confirmed by CT scan and enhanced examination were retrospectively analyzed. Results 10 cases of chromophobe carcinoma were unilateral single lesions. The largest diameter of tumor ranged from 2.5 cm to 6.9 cm with an average of 4.65 cm. Tumor density in 8 cases was slightly higher density or density, 2 cases were mixed density. 9 cases of enhanced renal parenchyma clear boundaries with the surrounding. 9 cases were convex growth. Six of the 6 tumors were round or round in shape, and 4 were underdeveloped, of which 3 were characterized by a characteristic “8” sign or hourglass sign. Tumors were mild to moderate enhancement, uniform or uneven way to strengthen, one case of internal wheel-like enhancement can be seen. All tumors had no perivascular infiltration, renal pelvis invasion, lymph nodes, renal vein involvement. Conclusion CT manifestations of chromophobe renal cell carcinoma have certain characteristics, and ultimately still need pathological diagnosis.
