Background: Cystic adenomyosis is an uncommon feature of adenomyosis, and women with the disease usually undergo laparotomy. We treated a case of cystic adenomyosis with radiofrequency ablation.
Case: A 21-year-old woman had severe dysmenorrhea supposedly caused by cystic adenomyosis. Under general anesthesia and ultrasound guidance, a radiofrequency needle was inserted into the cyst through the cervix, and the cyst was ablated. The procedures took about 15 minutes, with no complications. Lower abdominal pain and a high fever occurred 3 days later but disappeared soon after necrotic tissue was discharged. The cystic lesion disappeared, and the severity of the dysmenorrhea decreased by one-third as compared with that before the ablation.
Conclusion: This was the first case of cystic adenomyosis treated with radiofrequency ablation.
