【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 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.
目的 探讨甲状腺髓样癌的超声声像图特点，以提高超声诊断水平。 方法 回顾性分析2006年1月－ 2010年9月经手术切除及病理组织学证实的16例甲状腺髓样癌20个结节的超声声像图表现。 结果 20个甲状腺髓样癌结节中，结节呈低回声20个，结节内部有钙化灶者13个，结节内血流丰富者13个，合并有甲状腺乳头状微小癌1例，颈部淋巴结肿大17例。 结论 甲状腺髓样癌具有一定的超声声像图特点，了解这些特点可以提高超声对甲状腺髓样癌的诊断水平。
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.
