Unusual Case of a Torted Mesenteric Fibroid

Torsed retroperitoneal leiomyomas: A case report and review of literature

BACKGROUND

Retroperitoneal leiomyomas (RLs) are rare benign tumours that can occur in the pelvic and/or abdominal parietal retroperitoneum. Once torsion occurs, it causes acute abdominal pain and can even lead to serious consequences such as gangrene, peritonitis, haemoperitoneum and shock if not identified and treated promptly. Therefore, a better understanding of the characteristics of RL torsion is needed. Here, we present a case of acute pedicle torsion of an RL in the posterior peritoneum followed by a literature review.

CASE SUMMARY

Herein, we report the case of a 42-year-old woman with RL torsion. The patient visited our hospital complaining of lower abdominal pain for 6 d. Pelvic examination revealed a tender mass superior to the uterus. Pelvic magnetic resonance imaging (MRI) revealed an anterior uterine mass, multiple uterine fibroids and slight pelvic effusion. MRI suggested the possibility of a subserosal myoma of the anterior uterine wall with degeneration. Intraoperative exploration revealed a 10 cm pedunculated mass arising from the posterior peritoneum, with the pedicle torsed two times. Pathological examination confirmed a torsed RL.

CONCLUSION

In the case of a pelvic mass complicated with acute abdomen, the possibility of torsion should be considered.

Giant cellular leiomyoma in the broad ligament of the uterus: A case report

BACKGROUND

The treatment of large pelvic masses in postmenopausal women is a challenge in clinical practice. Although ultrasound or magnetic resonance imaging can be used to determine the size and location of the mass, it is still difficult to achieve a preoperative diagnosis. The majority of cellular leiomyomas are diagnosed by histopathology after surgery. We report the differential diagnosis and surgical management of a rare case of cellular leiomyoma in the broad ligament of the uterus.

CASE SUMMARY

A 52-year-old Chinese woman without sexual history was admitted to the First Affiliated Hospital of Guangzhou University of Chinese Medicine for the first time. The patient had a 1-year history of progressive abdominal enlargement as well as a 2-year history of menopause, and complained of frequent abdominal pain and low-grade fever. Computed tomography of the abdomen showed a solid cystic mass (29.4 cm × 18.8 cm × 37.7 cm) in the pelvis and abdomen. Moreover, routine blood test results indicated a baseline cancer antigen 125 (CA-125) level of 187.7 U/mL and C-reactive protein of 109.58 mg/L. Subsequently, retrograde hysterectomy and bilateral adnexectomy were performed in this patient. On histopathologic examination of the surgical specimen, a rare cellular leiomyoma in the broad ligament was diagnosed.

CONCLUSION

Clinicians need to constantly improve diagnosis and treatment for the challenges posed during clinical assessment, differential diagnosis, and surgical management.
