【摘要】 目的 分析超声对腺性膀胱炎的误、漏诊原因，探讨减少其误、漏诊的方法。 方法 回顾性分析2006年1月-2010年2月经病理证实的135例腺性膀胱炎的声像图表现。 结果 135例腺性膀胱炎患者中，超声误诊26例，误诊率19.3%，漏诊11例，漏诊率8.2%。误诊的主要原因：乳头结节型和团块型与膀胱肿瘤声像图极为相似、容易混淆，超声医师对膀胱壁各层次的观察不仔细，对病史重视不够；漏诊的主要原因：膀胱充盈不佳或不充盈，病变体积太小、位于前壁或顶部，或病变位于膀胱后壁及颈部被明显增生的前列腺、膀胱内血凝块及膀胱结石等掩盖。 结论 超声是诊断腺性膀胱炎常用方法，但存在一定的误、漏诊，改进检查方法，可减少其误、漏诊发生。【Abstract】 Objective To analyze the reasons of missed diagnosis and misdiagnosis of glandularis cystitis by ultrasonography. Methods The sonographic outcomes of 135 patients with glandular cystitis diagnosed by pathological examination from January 2006 to February 2010 were retrospectively analyzed. Results In 135 patients, misdiagnosis was in 26 with a rate of 19.3%, missed diagnosis was in 11 with a rate of 8.2%. The reasons of misdiagnosis included: the sonographic outcomes of mastoid and tuberculous conglomeration were similar to those of bladder tumour; the ultrasonographic professionals didn’t clearly observe each layer of the bladder wall, and didn’t pay enough attention to the disease history. The reasons of missed diagnosis included: the bladder was under-filled or unfilled, the size of the lesions were too small and were located at the anterior wall or the top, and the lesions were located at the posterior wall and neck of the bladder which were covered up by obvious prostate hyperplasia,and gores or stones of bladder so that the lesions could not be observed. Conclusion Ultrasonography is a usual method for diagnosing glandular cystitis,and we should ameliorate the examination to decrease the misdiagnosis and missed diagnosis.
Objective To investigate the reasons of misdiagnosis and missing diagnosis in blunt abdominal trauma (BAT), and to put forward effective preventive measures. Methods Literature on BAT diagnosis in recent years was reviewed. Results Misdiagnosis and missing diagnosis, which can take place in every segment of BAT patients, were still quite common nowadays. Conclusion Detailed case history collecting, faithful medical examination and making good use of assistant examinations can efficiently decrease the misdiagnosis and missing diagnosis rates of BAT patients.
Objective To investigate the imaging characteristics of endometrial polyps by using transvaginal ultrasound and analyze the causes of misdiagnosis. Methods Fifty-seven patients pathologically diagnosed of endometrial polyps were retrospectively analyzed. Results The endometrial polyps had its own characteristics of ultrasound images, especially the lesion, size, shape, echo, border, color Doppler flow imaging (CDFI) and so on. Conclusion Endometrial polyps has some special features on ultrasound image. Inspection in the secretary period, along with endometrial hyperplasia of the merger as well as multiple myoma the merger may result in misdiagnosis.
目的 探讨宫颈癌漏诊的原因及特点，提高首诊诊断率。 方法 回顾性分析2009年1月－2011年3月收治的外院漏诊的65例宫颈癌患者临床资料。 结果 漏诊的65例中有51例误诊为宫颈糜烂，其中仅13例首诊曾行细胞学筛查，16例行阴道镜检查及活检，总平均年龄仅39岁，农村居民54例。 结论 各地区应加强宫颈癌筛查意识，采取相应措施及适合的筛查方式提高宫颈癌筛查率，减少漏诊。
目的：通过超声对185例肾上腺肿瘤诊断及漏诊、误诊病例分析，寻找影响肾上腺肿瘤超声漏诊及误诊的因素。 方法：本文回顾性分析185例肾上腺肿瘤超声与病理的资料，对超声漏诊和误诊原因进行了分类、归纳和总结。结果：通过185例肾上腺肿瘤的超声检查，超声诊断出肾上腺病变122例，诊断正确率65.95%，明显低于相关文献报道，漏诊57例，误诊6例。漏误诊率(34.05%)，明显高于相关文献报道，综合分析其病理及影像学资料，将漏误诊原因归纳为五种：①左侧肾上腺肿瘤；②小于2.0 cm的肿瘤；③混合性回声的肿瘤；④临床及超声医师对肾上腺肿瘤认识不足；⑤误诊的主要原因是由于肿瘤巨大，造成定位困难。结论：通过对肾上腺肿瘤漏诊及误诊分析，可以提高超声诊断的准确性，降低漏误诊率。
