Objective: To identify the different sonographic findings on gray scale and color Doppler in tubo-ovarian abscesses (TOA) which confirmed by surgery and pathologic examinations.
Methods: Eighty women with surgically documented TOA were enrolled into this study. A retrospective review of their USG records was performed.
Results: The mass was demonstrated at the position of the ovary in 65 cases and at the cul-de-sac in 15 cases. The maximum diameter was 10cm. The mass was a simple cyst in 10 cases, in 10 cases it was cyst with septation, in 15 cases it was a thickend tube-shaped structure with multiple internal echoes and in 39 cases it was a mixture of cystic and solid elements. Pyosalpinges were found in 17 cases. Fluid in the cul-de-sac was observated in about half of the cases. Color doppler sonography demonstrated low impedance blood flow in the borders.
Conclusion: The USG findings of tubo-ovarian abscesses are not specific. However the presence of a mass at the ovary or cul-se-sac in combination with clinical findings is helpful for a correct diagnosis. Also the color doppler flow can further characterize the nature of pelvic mass by detecting a significant rich blood flow.
