Summary

A transvaginal scan (TVS) is performed with an empty bladder using a curvilinear, multifrequency, endocavity transducer with a typical central frequency of 6.5MHz. A fibroid outline is usually well visualized by TVS, even in the very small lesion, because of the pseudocapsule. The mixed tissue make-up of the fibroid produces a heterogeneous echo pattern on an ultrasound scan and can be highly attenuating of the ultrasound beam in some lesions. The most common gynecological symptoms of fibroids are menorrhagia and dysmenorrhea and, when significantly enlarged, they can also cause compression of adjacent pelvic structures. Most studies that have examined the relationship between fibroids and miscarriage rates have looked predominantly at intramural fibroids, with few data available on impact of submucosal fibroids. Myolysis is ablation of a fibroid mass by use of radiofrequency (RF) electricity, cryoprobes or focused ultrasound.
