摘要
目的：分析肾占位性病变的误诊原因及CT表现，探讨CT对该类疾病的鉴别诊断价值。方法：对手术、病理证实的21例误诊的肾占位性病变的CT表现进行回顾性分析。结果：肾恶性肿瘤13例，其中11例误诊为其他类型恶性肿瘤，2例误诊为良性病变。良性肿瘤5例，均误诊为肾癌。感染性病变3例，其中1例肾结核CT误诊为血管平滑肌脂肪瘤，2例肾脓肿CT均误诊为肾癌。结论：CT对肾占位性病变的诊断具有较大优势，对大部分肿块能准确诊断。但对少数表现不典型的肿块，应行术中冰冻切片或肾穿刺活检；随着技术的发展，各种影像学方法的功能成像均有可能为这类病变提供鉴别诊断的依据。
Abstract
Objective: To analyse the CT findings, misdiagnostic reasons of renal masses and to investigate the value of CT imaging in qualitative diagnosis of these diseases. Methods: Twenty-one cases of renal masses, proved surgically and pathologically, were analyzed retrospectively. Results: Thirteen cases were malignant tumors including 11 cases diagnosed as other malignant tumors and 2 cases diagnosed as benign tumors. Five cases were benign tumors diagnosed as renal cell carcinoma. Three cases were infection disease including 1 case renal tuberculosis diagnosed as angiomyolipoma and 2 cases of renal abscess diagnosed as renal cell carcinoma. Conclusion: Our study comfirmed that CT imaging is still useful in the diagnosis of renal masses. It is still difficult to determine some atypical renal masses. To avoid misdiagnosis, frozen biopsy or percutaneous biopsy may be helpful, functional parameters of lesions with different imaging modalities may be helpful in identifying these diseases in the future.
