目的分析膀胱内翻性乳头状瘤的声像学表现与诊断情况,以提高超声诊断符合率。方法对经病理检查证实的56例膀胱内翻性乳头状瘤的术前超声检查资料,进行回顾性分析。结果 56例膀胱内翻性乳头状瘤,术前超声检查发现病灶者55例,其中78.2%(43/55)位于膀胱三角区及周围,最大横径平均为(1.3±0.7)cm,超声表现为结节型、条带型、不规则型,多呈边缘较光整的均质高回声或中等回声,85.5%(47/55)病灶无血流信号或仅见少量血流信号,经腹壁超声检查38例误诊为膀胱癌。结论膀胱内翻性乳头状瘤的超声表现具有一定特征性,检查者应提高对该疾病的认识,避免误诊为膀胱癌。
Objective To analyze the sonographic features and diagnosis of inverted papilloma of the bladder to improve the coincidence rate of ultrasonic diagnosis. Methods The biopsy data of 56 cases of inverted papilloma confirmed by pathology were retrospectively analyzed. Results In 56 cases of inverted papilloma of the bladder, 55 cases were found by ultrasonography before surgery, of which 78.2% (43/55) were located in the trigone of the bladder and around the triangle. The maximum transverse diameter was (1.3 ± 0.7) cm on average. 85.5% (47/55) showed no or only a small amount of blood flow signals in nodular, banding, irregular and mostly edge-enhanced homogeneous hyperechoic or moderate echoes. The abdominal ultrasonography Check 38 cases misdiagnosed as bladder cancer. Conclusion Ultrasound of inverted papilloma has a certain characteristic, the examiner should raise awareness of the disease and avoid misdiagnosis as bladder cancer.
