Transvaginal ultrasound-guided biopsy of adenomyosis

Adenomyosis is a gynecologic disorder characterized by the presence of ectopic endometrial tissue within the uterine myometrium. It can involve most of the myometrium (diffuse adenomyosis), it may be present only in a circumscribed part of the myometrium (focal adenomyosis) or it may appear as a large cyst (adenomyotic cyst). The common sign of adenomyosis is uterine enlargement.
