Chinese Journal of Ultrasonography 2003;0(07):-
Objective To evaluate the usefulness of color Doppler ultrasonography in differential diagnosis of cervical lymphadenopathy by depicting the intranodal vascular pattern. Methods One hundred and twenty lymph node lesions in 113 patients who underwent color Doppler flow imaging were grouped as reactive lymphadenitis ( n =25), tuberculosis ( n =14), lymphoma ( n =41), and metastasis ( n =40). The vascular patterns of hilar type, central type, peripheral type and mixed type were assessed. Results Most reactive lymph nodes( 92.0%) and lymphomatous nodes( 75.6%) showed hilar vessels,lymphomatous nodes also frequently demonstrated peripheral vessels( 75.6%).Central vessels or peripheral vessels were frequent in metastatic nodes( 60.0% and 57.5%, respectively).The intranodal vascular distribution in tuberculous nodes was simulated malignant disease. Avascularity was observed in 2 of 25 reactive lymph nodes and 1 of 14 tuberculous nodes. Conclusions Central vessels or peripheral vessels were mainly found in malignant lymphadenopathy,and the presence of hilar vessels is suggestive of benign lymphadenopathy. However, there is overlap of appearance between benign and malignant disease.

ObjectiveTo investigate the value of ultrasonography in the diagnosis of the papillary thyroid microcarcinoma (PTMC) in patients with Hashimoto’s thyroiditis (HT).MethodsThis retrospective study used data from Ruijin Hospital of Shanghai Jiaotong University of Medicine during November 2012 to December 2013. A total of 111 small thyroid nodules (75 PTMC/36 benign nodules) with 107 HT cases which were pathologically conifrmed were included in this study. The sonographic characteristics of nodules were investigated, including nodule aspect ratio, shape, border, margin, acoustic halo, internal structure, echo level, microcalciifcations, rear acoustic attenuation, vascular pattern and extent of the blood supply and the types of thyroid tissue echogenicity. Chi-square test and Fisher′s exact probability method was used to compare the differences of the sonographic characteristics between the benign nodules and malignant nodules. With surgical pathology as the gold standard, computing the value of ultrasonography in the diagnosis of PTMC with HT, including the sensitivity, speciifcity, diagnostic accuracy, positive predictive value and negative predictive value.ResultsA total of 111 thyroid tiny nodules (75 PTMC/36 benign nodules) with 107 HT cases which were pathologically conifrmed were included in this study. The results showed 111 small thyroid nodules as solid hypoechoic. Four indexes between PTMC and benign nodules had statistical signiifcance, such as margin, microcalciifcations, vascular pattern and extent of the blood supply. The other six indexes between PTMC and benign nodules had no statistical significance, such as aspect ratio, shape, border, acoustic halo, rear acoustic attenuation and the types of thyroid tissue echogenicity. Ultrasound diagnostic accuracy of small tyroid nodules in patients with HT was 74.77% (83/111). The sensitivity, specificity, diagnostic accuracy, positive predictive value and negative predictive value of the ultrasound diagnosis of PTMC were 93.33% (70/75), 36.11% (13/36), 74.77% (83/111), 75.27% (70/93), and 72.22% (13/18), respectively.ConclusionsCompared with general population, some classic ultrasound features became less effective in patients with HT. However, ultrasonography has some differential diagnostic value in these cases.

Objective To explore the pathological basic of some common characteristic of papillary microcarcinoma of thyroid in ultrasound. Methods Totally 117 thyroid papillary microcarcinomas that were completed all thyroid ultrasound examinations before the surgical excisions were collected. Shape, border, internal echogenicity, halo, posterior echogenicity and calciifcation were observed in ultrasound. While the degree of inifltration of the tumor, the tumor’s internal structure as well as calciifcation was observed in pathology. Results IIrregular shape (87.18%, 102/117), unclear border (80.34%, 94/117), hypoechoic (90.60%, 106/117) and microcalciifcations (65.81%, 77/117) were recognized by ultrasound while the main pathological features were invasive growth (93.16%, 109/117), cell components internally (46.15%, 54/117) and calciifcation (56.41%, 66/117). Of the 109 neoplasms which were invasive growth in pathology, 102 (93.58%) nodules presented irregular shape in ultrasound while 91 (77.78%) presented unclear border. All of the 8 neoplasms which were not invasive growth in pathology showed regular shape in ultrasound. Thirteen nodules showed halos in ultrasound, and 8 of them showed visible ifbrous capsule surrounding the mass. Whatever the tumor’s internal structure was, most nodules presented hypoechoic. And the hyperechoic nodules were all found cell components internally. Of the 66 neoplasms which were found calciifcation by microscope, 35 (53.03%) nodules showed calciifcation in ultrasound and 31 (46.97%) did not. And of the 51 neoplasms in which calciifcation were not found by microscope, 42 (82.35%) nodules showed calciifcation in ultrasound and 9 (17.65%%) did not. Conclusions There is no doubt that all the performances of papillary microcarcinoma in ultrasound have bases in pathology. It is helpful to the judgment of a thyroid nodule if we could understand the correlation of performances in ultrasound and pathology.
