MR imaging of endometrial stromal sarcoma: Correlation with pathologic findings

OBJECTIVE. This study describes MR imaging of eight patients with endometri al stromal sarcoma and correlates the imaging findings with histopathologic findings. To our knowledge, the radiologic findings of this entity have no t been reported in the literature. CONCLUSION. Endometrial stromal sarcoma typically presents with extensive m yometrial involvement, which is either sharply demarcated or diffusely infi ltrative. Bands of low signal intensity are observed within the areas of my ometrial involvement on T2-weighted images. These bands correspond to the p reserved bundles of myometrium on pathologic examination. Tumor extension a long the vessels or ligaments is another characteristic of MR imaging of en dometrial stromal sarcoma.
