Abstract
BACKGROUND

A cystic lesion arising from the myometrium of the uterus, termed as cystic adenomyosis, has chocolate-like, thick viscous contents and contains various amounts of endometrial stroma below the glandular epithelium. It is an extremely rare type of adenomyosis.

CASE SUMMARY

Herein, we report an unusual case of a giant cystic mass in the pelvic cavity after uterine myomectomy. The patient complained of abnormal uterine bleeding and severe dysmenorrhea. After a levonorgestrel-containing intrauterine device (LNG-IUD) was inserted, her symptoms were greatly alleviated. However, the LNG-IUD was detected in the cystic cavity during the follow-up. For fear of the intrauterine device migrating into and damaging the surrounding viscera, surgical treatment was proposed. Therefore, laparoscopic resection of the lesion and removal of the LNG-IUD were performed and cystic adenomyosis with an LNG-IUD out of the uterine cavity was diagnosed.

CONCLUSION

We believe that myomectomy breaking through the endometrial cavity may have been a predisposing factor for the development of cystic adenomyosis in this case.

Core tip: Myomectomy breaking through the endometrial cavity may be a predisposing factor for the development of adenomyosis. A Mirena may provide effective therapeutic action for any pelvic endometrial deposit in different ways. In terms of management, laparoscopic uterine-sparing intervention may be a preferable choice for exophytic cystic adenomyosis.
