Abstract
We report a case of an intrauterine tumor mass caused by an embedded intrauterine device (IUD). The patient was preoperatively diagnosed as a submucous leiomyoma of the uterus and underwent a hysteroscopic myomectomy. We discovered the IUD postoperatively inside the submucous leiomyoma. The patient is a 73 years old gravida 2, para 2. She had a history of hypertension and was on oral medication. She had forgotten that she had undergone an IUD insertion. At her clinic visit, her chief complaint was metrorrhagia. An endometrial polyp was suspected and she was referred to our hospital. A transvaginal ultrasound examination imaged a tumor-like lesion in the uterine cavity with both hypoechoic and hyperechoic areas. Magnetic resonance imaging (MRI) showed a well-circumscribed tumor with focal high signal intensity in T2 weighted images. Both the cervical and endometrial cytology were negative at her previous clinical examination. We performed an outpatient hysteroscopy and found a pedunculated mass at the uterine fundus. The preoperative diagnosis was a submucous leiomyoma; she underwent a myomectomy via operative hysteroscopy under general anesthesia. Complete resection of the myoma was performed, and an IUD was discovered inside the resected myoma. She had a benign postoperative course, and no post-myomectomy adhesions developed.
