ABSTRACT
BACKGROUND: Abdominal wall endometriosisï¼AWEï¼is an unusual extra-pelvic endometriosis. Currently, multiple treatment modalities are available, but no clear guidelines exist for the management of large AWE. MATERIALS AND METHODS: We present a 36-year-old female patient with a large AWE lesion who underwent cesarean section due to abnormal fetal position 8 years ago. The mass lesion of AWE located in rectus muscle fascia and rectus muscle with a size of 61 × 25 × 49mm. RESULTS: HIFU treatment was completed in one session. One day post-HIFU MRI showed the mass was completely ablated. After HIFU treatment, the cyclical abdominal pain disappeared. The mass lesion shrank during follow-up period and disappeared in 1 year after HIFU. No complication was observed after HIFU. CONCLUSION: Surgical resection of AWE remains the standard of care. In patients with large AWE lesion located in rectus muscle fascia and rectus muscle where the muscle and fascia must be excised, HIFU treatment should be considered to avoid mesh implantation.
