Summary
Distinguishing uterine sarcomas from fibroids preoperatively is crucial. Modern imaging like ultrasound and MRI can identify malignant features, guiding surgical decisions and improving patient outcomes.
Area of Science:
- Gynecologic Oncology
- Diagnostic Imaging
- Pathology
Background:
- Uterine mesenchymal tumors require accurate preoperative differential diagnosis.
- Imaging modalities play a key role in surgical planning and fertility preservation.
Purpose of the Study:
- To review the strengths and limitations of modern imaging techniques for preoperative diagnosis of uterine mesenchymal tumors.
- To guide the selection of appropriate surgical procedures based on imaging findings.
Main Methods:
- Review of current literature on ultrasound and magnetic resonance imaging (MRI) for uterine tumor characterization.
- Analysis of imaging features associated with uterine sarcomas versus fibroids.
- Discussion of the role of biopsy and other imaging modalities (PET-CT, CT).
Main Results:
- Ultrasound and MRI reveal specific features of uterine sarcomas, including non-homogenous structure, irregular borders, and vascularity.
- Diffusion-weighted imaging (DWI/MRI) shows restricted diffusion in sarcomas, though with overlap with some fibroids.
- Biopsy may be necessary for definitive diagnosis in suspicious cases, especially when fertility preservation is desired.
Conclusions:
- Uterine sarcomas can be differentiated from fibroids using a combination of ultrasound and MRI findings.
- Accurate preoperative diagnosis is essential to tailor surgery and avoid complications like iatrogenic tumor spread from morcellation.
