Abstract To evaluate the clinical value of B-mode ultrasonography in the diagnosis of twisted ovarian tumor and find out some ultrasonographic diagnostic criteria, methods to examine acute abdominal pain with pelvic cavity emphasized. In comparision with more than 40 years old groups and other different groups, the differences were significant at incidence (P<0.01 & P<0.05). The ultrasonographic features were as follow: ① Ovary of the affected side disappeared. Sonographic examination displayed an abnormal pelvic or low abdominal masses; ②The masses were usually at the midline of abdomen, anterior to the uterus or at the base of pelves; ③The masses were medium sized (mean diameter: 9.1 cm), cystic and mixed masses were common; ④Echoes of CDFI in the masses were decreased or disappeared; ⑤Presence of tenderness when probe was pressed on the affected side in some cases, fluid accumulation of uterine-rectal cul-de-sac. The coincidence rate of ultrasonography was 85% (72/85). It is suggested that B-mode ultrasonography provides valuable information for the early diagnosis of twisted ovarian tumor and differential diagnosis of pelvic masses.
