May demonstrate a dilated fallopian tube where altered blood products within the tube are often demonstrated as homogeneous low-level echoes.
Blood products within the distended fallopian tube may be seen as high attenuation on CT.
The distended tube can be high signal intensity on T1-weighted fat-suppressed imaging due to blood products. Blood products may cause adhesions to fold or pull the ovaries and fallopian tubes toward the midline, a finding known as the “kissing ovary” sign. The adhesions may also encase the ovary, resulting in an appearance similar to that of a complex cystic solid mass, although this feature is not specific.
