Value of ultrasonography and magnetic resonance imaging for the characterization of uterine mesenchymal tumors

Objective To evaluate ultrasonography and magnetic resonance imaging (MRI) performance in differentiating benign leiomyomas from malignant mesenchymal or mixed tumors (MMT) and smooth muscle tumors of uncertain malignant potential of the uterus (STUMP). Design Retrospective cohort study. Setting Uni...

Description
Summary:Objective To evaluate ultrasonography and magnetic resonance imaging (MRI) performance in differentiating benign leiomyomas from malignant mesenchymal or mixed tumors (MMT) and smooth muscle tumors of uncertain malignant potential of the uterus (STUMP). Design Retrospective cohort study. Setting University hospital, France. Population One hundred and eight women who underwent imaging before surgery for uterine mesenchymal tumor (85 with benign leiomyomas and 23 with MMT/STUMP). Methods The ultrasonography reports were reviewed. Conventional, perfusion and diffusion MRI were blindly analyzed. Recursive partitioning analysis (RPA) was performed to construct diagnostic flowcharts. Main outcome measures Accuracy of a diagnostic flowchart. Results At ultrasonography, single tumor, non‐myometrial origin, absence of acoustic shadowing, thickened endometrium and ascites were associated with MMT/STUMP (p = 0.001, p
