Objective:

To report a case of parasitic uterine leiomyoma attached to the small bowel mesentery, highlighting its diagnostic challenges and significance in clinical practice.

Key Findings:
  • Parasitic leiomyoma can mimic gastrointestinal tumors, complicating diagnosis and potentially leading to unnecessary surgeries.
  • The patient had a history of laparoscopic myomectomy, which is associated with the development of parasitic leiomyomas, underscoring the need for awareness in similar cases.
  • Histopathological examination confirmed the mass as a parasitic uterine leiomyoma with red degeneration, providing critical insights for future cases.
Interpretation:

Differentiating parasitic uterine leiomyomas from gastrointestinal tumors based on imaging alone is challenging, especially in patients with a history of uterine surgery, which can lead to significant clinical implications if misdiagnosed.

Limitations:
  • The case study is based on a single patient, limiting generalizability and the ability to draw broader conclusions.
  • The diagnostic process relied heavily on imaging, which may not always accurately distinguish between tumor types, highlighting the need for further research.
Conclusion:

Parasitic uterine leiomyoma should be considered in the differential diagnosis of abdominal masses in patients with a history of uterine surgery, particularly after morcellation, to prevent unnecessary radical resection.
