ABSTRACT
Objective To observe the ultrasonographic features of primary female genital system lymphoma and its histopathological characteristics.Methods Sonographic appearances and histopathological characteristics of 14 patients who were pathologically comfirmed as primary female genital system lymphoma were reviewed.Results Fourteen patients underwent ultrasonography and 15 lesions were found,6 cases of which were found in the ovary and cervix separately,3 cases in the uterine body.Among the lesions detected,10 of which respectively represents extremely low echo and homogeneous internal echo,all lymphomas had posterior enhancement.The margins were most frequently circumcribed (13/15),5numbers primary lymphomas of the ovary were mostly elliptical in shape,while 5 numbers of cervix tumors showed the shape of lobular,all of the tumors in the uterine body showed diffuse symmetrical enlargement without disruption of the endometria.Color Doppler imaging showed hypervascularity in most tumors(13/15).The pathological examination showed that all tumors were non-Hodgkin lymphoma diffuse B-cell type.Conclusions Primary female genital system lymphoma has some ultrasonic features,including extremely low echo,homogeneous echo and posterior enhancement.Final diagnosis depends on the histopathology.
ABSTRACT
ObjectiveTo investigate the value of strain ratio (SR) in the diagnosis of Hashimoto's thyroiditis.Methods 116 patients who had been diagnosed clinically as Hashimoto' s thyroiditis were enrolled in the study.Those patients were classified into four groups:the hyperthyroidism group,the euthyroidism group,the subclinical hypothyroidism group,and the clinical hypothyroidism group.50volunteers with normal thyroid functions were enrolled as a control group.SR of the thyroid and sternocleidomastoid muscle of same side was calculated.The correlation coefficient between the elasiticity SR and the serum thyroid stimulating hormone (TSH) was evaluated and their differences in the diagnosis of Hashimoto's thyroiditis were compared.ResultsThe Spearman's correlation coefficient between the SR and the serum TSH was 0.605,which was significant (P =0.000).The SR increased in an ascending order among the group with hyperthyroidism,the control group,the group with euthyroidism,the group with subclinical hypothyroidism,and the group with clinical hypothyroidism.ConclusionsElastography SR is valuable way for evaluating the progression of Hashimoto's thyroiditis.
