Navigating diagnostic challenges: case reports on differentiating uterine fibroids from leiomyosarcoma through imaging and clinical evaluation.

Abstract

Background: Differentiating between uterine fibroids and leiomyosarcoma poses significant challenges, particularly in cases of atypical fibroid degeneration. Accurate diagnosis is crucial for appropriate treatment and patient outcomes.

Methods: We present two case reports to illustrate the complexities involved in distinguishing these conditions. Both cases involved patients with similar clinical presentations and imaging findings. The diagnostic process included trans-abdominal and trans-vaginal ultrasound, CT scans, and histopathological examination.

Results: In Case 1, the patient presented with worsening abdominal pain and imaging revealed multiple myomas. Histological examination confirmed benign fibroids following surgery. Case 2 involved a patient with an abdominal mass and CT findings suggestive of a fibroid. However, ultrasound characteristics raised suspicion of malignancy, and subsequent histopathological analysis confirmed leiomyosarcoma.

Conclusion: These case reports underscore the importance of combining clinical evaluation with advanced imaging techniques for accurate differentiation between uterine fibroids and leiomyosarcoma. While ultrasound plays a critical role, its effectiveness is enhanced by the experience of the sonographer and the integration of other diagnostic modalities. Future multicenter studies should focus on refining these diagnostic approaches to improve accuracy and patient outcomes.
