Objective      To study the imaging features of female pelvic splenosis using ultrasonography. Methods     The clinical and sonographic data of 3 cases

a total of 7 masses histopathologically proved as pelvic splenosis

were retrospectively analyzed. Results     There were 71.43%（5/7）of pelvic splenosis found to localize to the right ovary and 28.57%(2/7) to the left ovary. Two-dimensional gray-scale sonographic imaging revealed a slightly stronger homogeneous echo in the pelvic cavity compared to the echoes detected in the myometrium. The masses were non-cystic showing clear boundary with capsule. The color Doppler ultrasonography showed sufficient blood supply of the masses. The degree of blood flow was graded to Adler Ⅱ and Ⅲ

accounting for 57.14%(4/7) and 42.86%(3/7)

respectively. The resistance index (RI) of blood flow measured in 5 pelvic splenosis was moderate（RI：0.55～0.63）. Conclusion     The ultrasonographic imaging of pelvic splenosis is featured with homogeneous echo pattern

which is a slightly stronger than echo in myometrium. The blood flow is classified to Adler Ⅱ~Ⅲ grade with moderate resistance. The typical sonography features combined with splenectomy history is important for the diagnosis of pelvic splenosis and distinguishing it from other gynecological disease.
