Abstract
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.

Core Tip: Retroperitoneal leiomyoma torsion is extremely rare. We report a case of acute pedicular torsion of a leiomyoma in the posterior peritoneum, followed by a literature review. The review suggested that RL torsion mainly occurs in female patients, and the most prominent clinical symptom is abdominal pain. The possible imaging features of torsed retroperitoneal leiomyomas include a well-circumscribed mass separate from the uterus and adnexa, no enhancement, a torsed pedicle, and ascites. If the diagnosis is unclear, surgical exploration should be considered to confirm the diagnosis in a timely manner to reduce the risk of other complications.
