Ultrasound-guided drainage and sclerosis of a cystic myometrial mass

Cystic adenomyoma surgery

OBJECTIVE

Cystic adenomyoma is a lesion located within the myometrium. It is lined with endometrium and has hemorrhagic content. This rare entity has been described as a focal form of adenomyosis. However, it is poorly understood, and the management of symptomatic patients is not codified. Our objective is to evaluate the effectiveness of treatment with planned surgery for cystic adenomyoma on symptoms and fertility in a retrospective series of patients.

STUDY DESIGN

This is a retrospective study between January 2011 and January 2018 in a university hospital of patients that had surgery for cystic adenomyoma with uterine preservation.

RESULTS

Pre-operative, per-operative, and post-operative data were recorded. Of the 18 patients included, 3 were lost to follow-up; 15 underwent laparoscopic surgery and 3 operative hysteroscopies. Complications during and after surgery were rare, involving only 3 patients, and of low severity. One patient saw no improvement in pain after surgery and 2 patients saw only partial improvement in their pain; 7 patients achieved at least one pregnancy with favorable outcome after surgery.

CONCLUSION

Based on this series, we argue that conservative surgical treatment for cystic adenomyoma generally improves pain and fertility without causing morbidity.

Imaging in gynecological disease (21): clinical and ultrasound characteristics of accessory cavitated uterine malformations

OBJECTIVE

To describe the clinical and ultrasound characteristics of accessory cavitated uterine malformations (ACUMs).

METHODS

This was a single-center observational study of consecutive patients diagnosed with an ACUM, who had undergone an ultrasound examination by an experienced ultrasound examiner between January 2013 and May 2019, identified retrospectively from medical records. ACUM was diagnosed when a cavitated lesion with a myometrial mantle and echogenic contents was seen within the anterolateral wall of the myometrium beneath the insertion of the round ligament. In all women, presenting symptoms and clinical history were recorded along with detailed descriptions of the lesions and any concomitant pelvic abnormalities.

RESULTS

Twenty patients diagnosed with an ACUM were identified. Median age was 29.2 (interquartile range, 25.0-35.8) years. None of the women was premenarchal or postmenopausal. All of the women reported painful periods or pelvic pain and none of them reported subfertility. Twelve of the ACUMs were in the right anterolateral myometrium and eight were in the left anterolateral myometrium. Both a myometrial mantle and a fluid-filled cavity were considered to be defining features on ultrasound. The fluid contained within the cavity was either echogenic with a ground-glass appearance or hyperechoic. All of the lesions were spherical in shape. The Doppler flow seen in the outer rim was not markedly different from that of the surrounding myometrium, and the content of the cavity was avascular on Doppler examination. The mean outer cavity diameter of the ACUMs was 22.8 (95% CI, 20.9-24.8) mm and the mean internal cavity diameter was 14.1 (95% CI, 12.2-16.1) mm. Four women opted for transvaginal ultrasound-guided alcohol sclerotherapy. Surgical excision was carried out in eight cases, and the diagnosis was confirmed on histopathological examination in all of them.

CONCLUSIONS

ACUMs are a uterine abnormality with a distinct ultrasound appearance, which are associated with dysmenorrhea and chronic pelvic pain. Knowledge of their typical appearance on ultrasound could facilitate early detection and treatment. There are several treatment options for ACUM, ranging from simple analgesia to complete excision. Further prospective and longitudinal studies are required to study the prevalence and natural history of this condition. © 2020 International Society of Ultrasound in Obstetrics and Gynecology.
