【摘要】 目的 探讨超声显像对肾上腺肿瘤的定位、定性诊断与鉴别诊断价值。 方法 对 2003年1月-2009年1月125例疑为肾上腺肿瘤患者进行超声及CT检查，并经手术与病理证实。超声显像诊断后经手术与病理证实为嗜铬细胞瘤48例，肾上腺皮质腺瘤41例，皮质腺癌11例，肾上腺转移癌 9例，髓样脂肪瘤8例，结节样增生2例，肾上腺结核4例，胰尾部肿瘤1例，肝脏肿瘤1例，肾上极肿瘤1例。 结果 肾上腺肿瘤的病理类型不同，声像图表现亦各不相同。超声显像定位诊断符合率为96.0%（120/125），定性诊断符合率为91.2% （114/125）。 结论 超声显像对肾上腺肿瘤的定位与定性诊断价值较大，可作为临床诊断的首选检查方法。【Abstract】 Objective To assess the value of ultrasonography in the diagnosis and differential diagnosis of tumors of adrenal gland. Methods From January 2003 to January 2009, 125 patients who were suspected to suffering from adrenal tumors underwent ultrasonography and CT examination. The results were then confirmed by surgery and pathology. There were 48 cases of pheochromocytoma, 41 adenoma, 11 adenocarcinoma, 9 metastatic tumor, 8 adrenal medullary lipoma, 2 nubblar hyperplasia, 4 tuberculosis of adrenal gland, 1 tumor of cauda pancreatic, 1 tumor of liver and 1 tumor of upper pole of kidney. Results The ultrasonographic features varied with different pathological types. The accuracy diagnosis of localizition and qualitation were 96.0% (120/125) and 91.2% (114/125) respectively. Conclusion Ultrasonography is useful in diagnosing tumors of adrenal gland, which may be used as the first choice for the disease.
【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.
【摘要】 目的 探讨弹性成像在甲状腺微小癌诊断中的应用价值。 方法 回顾性分析从2007年12月-2008年4月间经病理证实的10例甲状腺微小癌患者共11个病灶的超声表现。 结果 彩色多普勒超声诊断甲状腺微小癌8例8个病灶，利用弹性成像技术诊断10例10灶。传统彩色多普勒超声对甲状腺微小癌的诊断率为72.7%；利用弹性成像技术对甲状腺微小癌的诊断率为90.9%。 结论 弹性成像技术对于甲状腺微小癌是对彩色多普勒超声检查的有益的补充，能够显著提高超声对甲状腺微小癌诊断的准确性。【Abstract】 Objective To evaluate the application of US-elastography in diagnosis of thyroid microcacinoma. Methods The images of color ultrasound and ultrasound elastography from 11 lesions of 10 patients with thyroid micro-carcinoma diagnosed via histopathology between December 2007 and April 2008 were retrospectively analyzed. Results Eight patients with eight lesions were found by colour ultrasound and 10 patients with 10 lesions were observed by ultrasound elastography. The diagnosis accurate rate of ultrasonography was about 72.7% and of ultrasound elastography was about 90.0%. Conclusion US-Elastography is a beneficial addition in diagnosis of thyroid microcacinoma by colour ultrasound. It can remarkably develop the accurate rate of the diagnosis of the disease.
Objective To discuss the diagnostic and differential diagnostic value of ultrasonography for primary testicular lymphoma (PTL) by studying the ultrasonographical image characteristics. Methods Thirty-one patients with PTL confirmed by postoperative histopathology between 2005 and 2015 were chosen to be the study subjects. We retrospectively analyzed their ultrasonographical features and clinical data. Results Most PTL patients were elderly men, and the initial symptom was mainly painless testis enlargement. Thirty-nine testicles were involved in the primary testicular lymphoma, including 23 unilateral and 8 bilateral. In the 31 patients, 22 had diffuse lesions and 9 nodal. Ultrasonography showed that most tumors were hypoechoic lesions, and part of them were hyperechoic linearly. The lesions had abundant blood flow signals with a low resistance index. Conclusions In elderly patients with painless testicular enlargement, the possibility of primary testicular lymphoma must be fist considered. Manifestations of primary testicular lymphoma have some distinctive characteristics, and combined with clinical history, they are helpful for the diagnosis and differential diagnosis of PTL.
