摘要
目的：探讨分析肾嗜酸细胞瘤（renal oncocytoma，RO）的cT表现并与病理结果对照，以提高对本病的诊断水平。方法：回顾性分析9例肾嗜酸细胞瘤的临床、影像及病理学资料，并复习相关文献。结果：本组9例肾嗜酸细胞瘤均为单发肿瘤，其中右侧4例、左侧5例；肿瘤最大径3．1—9．3cm，平均约5．6cm。CT平扫：肿块呈等或稍低密度，体积较小者密度相对均匀，较大者内部可见条索状、星芒状低密度灶；病灶边界欠清晰，1例出现肾周筋膜增厚，肾周脂肪间隙密度不规则增高，并见颗粒状钙化。增强扫描：9例肿块实性成分动脉期均明显强化，实质期强化程度稍降低，但均低于肾皮质；其中5例可见包膜强化，边界变清晰，7例肿块内部见无明显强化的星芒状瘢痕。结论：肾嗜酸细胞瘤血供丰富，强化明显，呈“快进慢出”型，部分肿瘤内部伴无明显强化的星芒状瘢痕，CT表现有一定特征.
Objective To compare CT features of renal oncocytoma （RO） with pathological findings in order to improve its diagnosis. Methods Nine RO patients had their clinical, imaging and pathological materials analyzed retrospectively, and related literatures were reviewed. Results In the nine solitary tumor patients, there were 4 cases on the right kidney and the remained 5 ones on the left. Maximum tumor diameter ranged from 3.1 to 9.3 cm, with the mean value of 5.6 cm. Plain CT scan found that the lumps showed isodensity or slightly low density, and that the lumps with small volumes had relatively densities while the ones with big volumes had streak or stellate low-density lesions amt unclear boundaries, and that one patient showed thickened perirenal fascia, irregularly increased preirenal fat space denstity and granular caleification. Enhancement scan proved that the solid parts of the tumor were enhanced obviously at arterial phase and slightly at parenchymal phase which were lower than the renal cortex, and that five patients had enhanced amicula and clear boundaries, and that seven patients had non-enhanced stellate cicatrix in the lumps. ConchuslonRenal oncocytoma has CT features as strong blood supply, obvious enhancement, fast-in and slow-out manifestations, and non-enhanced stellate cicatrix in some lumps.
