Ultrasonographic features and histopathological characteristics of primary female genital system lymphoma / 中华超声影像学杂志

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.
