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.
【摘要】 目的 探討超聲顯像對腎上腺腫瘤的定位、定性診斷與鑒別診斷價值。 方法 對 2003年1月-2009年1月125例疑為腎上腺腫瘤患者進行超聲及CT檢查，并經手術與病理證實。超聲顯像診斷后經手術與病理證實為嗜鉻細胞瘤48例，腎上腺皮質腺瘤41例，皮質腺癌11例，腎上腺轉移癌 9例，髓樣脂肪瘤8例，結節樣增生2例，腎上腺結核4例，胰尾部腫瘤1例，肝臟腫瘤1例，腎上極腫瘤1例。 結果 腎上腺腫瘤的病理類型不同，聲像圖表現亦各不相同。超聲顯像定位診斷符合率為96.0%（120/125），定性診斷符合率為91.2% （114/125）。 結論 超聲顯像對腎上腺腫瘤的定位與定性診斷價值較大，可作為臨床診斷的首選檢查方法。【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 探討彈性成像在甲狀腺微小癌診斷中的應用價值。 方法 回顧性分析從2007年12月-2008年4月間經病理證實的10例甲狀腺微小癌患者共11個病灶的超聲表現。 結果 彩色多普勒超聲診斷甲狀腺微小癌8例8個病灶，利用彈性成像技術診斷10例10灶。傳統彩色多普勒超聲對甲狀腺微小癌的診斷率為72.7%；利用彈性成像技術對甲狀腺微小癌的診斷率為90.9%。 結論 彈性成像技術對于甲狀腺微小癌是對彩色多普勒超聲檢查的有益的補充，能夠顯著提高超聲對甲狀腺微小癌診斷的準確性。【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 探討甲狀腺髓樣癌的超聲聲像圖特點，以提高超聲診斷水平。 方法 回顧性分析2006年1月－ 2010年9月經手術切除及病理組織學證實的16例甲狀腺髓樣癌20個結節的超聲聲像圖表現。 結果 20個甲狀腺髓樣癌結節中，結節呈低回聲20個，結節內部有鈣化灶者13個，結節內血流豐富者13個，合并有甲狀腺乳頭狀微小癌1例，頸部淋巴結腫大17例。 結論 甲狀腺髓樣癌具有一定的超聲聲像圖特點，了解這些特點可以提高超聲對甲狀腺髓樣癌的診斷水平。
