The role of clinical parameters and diffusion magnetic resonance in preoperative evaluation of leiomyomas

Comparing the role of diffusion-weighted imaging magnetic resonance (DWI-MR) in leiomyomas (LM), which can be in pathologically different variants such as cellular, mitotic active, atypical myoma (bizarre nuclei) and STUMP (smooth muscle tumors of uncertain malignant potential), to clinical findings for determining the malignant potential of myoma. Fifty patients who were diagnosed with myoma uteri between March 2013 and April 2017 and evaluated with DWI-MR in the preoperative period were included in the study. Clinical parameters and DWI-MR evaluations of LMs and atypical LMs were compared. While there was no difference in the clinical parameters between LM and atypical LM, there was a significant difference between abnormalities detected by DWI-MR (diffusion restriction, hypervascularity) (p = 0.012). DWI-MR may be a guide for preoperative leiomyoma evaluation, especially in patients who are planned to sustain fertility.
