Acute abdomen caused by torsion of a giant parasitic ovarian leiomyoma: A clinical case report

In plain language

Leiomyomas are benign smooth muscle tumours that typically arise in the uterus, but they can occasionally develop in extra-uterine locations. When they occur in atypical sites, establishing an accurate preoperative diagnosis becomes difficult because they can mimic other adnexal conditions. A woman of reproductive age experienced sudden, severe lower abdominal pain alongside symptoms characteristic of an acute abdomen. Diagnostic imaging showed an adnexal mass with indicators of ovarian torsion. During an emergency laparotomy, surgeons identified a solid mass inseparable from the ovary and performed a salpingo-oophorectomy. Histopathological examination subsequently confirmed the mass to be an ovarian leiomyoma that had undergone torsion. The findings highlight the importance of including ovarian leiomyomas in differential diagnoses for solid adnexal masses and emphasise that rapid surgical intervention is necessary to avert complications from tissue ischemia.

Key takeaways

  • Ovarian leiomyomas are rare benign tumours that can present clinically as an acute abdomen.
  • Atypical locations make preoperative differentiation from other solid adnexal pathologies challenging.
  • Definitive diagnosis requires postoperative gross and histopathological analysis.
  • Prompt emergency surgery is critical to manage ovarian torsion and avoid complications from ischemia.

Why it matters

Benign tumours that appear in unexpected parts of the body can closely resemble malignant or other urgent conditions. This report highlights how rare ovarian masses can cause severe medical emergencies like organ torsion. Recognizing these unusual presentations helps gynaecologists and surgeons make timely decisions, perform effective emergency surgeries, and protect reproductive-aged patients from tissue damage caused by delayed diagnosis.

Commercialisation angle

The abstract does not indicate an application pathway, as it reports a single clinical case rather than a commercial product or technology.

Abstract

Introduction: Leiomyomas are benign smooth muscle tumors most commonly originating from the uterus, but on rare occasions, they can develop in extra-uterine sites. Such atypical presentations may complicate preoperative diagnosis, particularly when mimicking other adnexal pathologies. We report a rare case of an ovarian leiomyoma presenting as an acute abdomen, highlighting the diagnostic and surgical challenges encountered. Case Description: A reproductive-aged woman presented with sudden-onset severe lower abdominal pain and clinical features consistent with an acute abdomen. Imaging revealed an adnexal mass with features suggestive of ovarian torsion. Emergency laparotomy identified a solid mass inseparable from the ovary. Salpingo-oophorectomy was performed. Gross and histopathological examination confirmed the diagnosis of an ovarian leiomyoma with torsion. Conclusion: Although ovarian leiomyomas are rare, they should be considered in the differential diagnosis of solid adnexal masses, especially in cases presenting with acute abdomen. Preoperative differentiation from other ovarian tumors is challenging, and definitive diagnosis relies on histopathology. Prompt surgical intervention remains crucial to prevent complications related to torsion and ischemia.
