Patient Data

Age: 70 years
Gender: Female

There is a mass in the endometrial cavity. It shows heterogeneous high signal on T2, heterogeneous low signal on T1 compared with myometrium, enhances less than myometrium on T1C+; a single feeding vessel extends to the mass consistent with pedicle artery sign.
The lesion appears to invade the anterior myometrial wall.

The anterior abdominal wall hernia is seen.

The mass measuring 10x26 mm

Case Discussion

This case demonstrates the imaging features of endometrial polyps with pedicle artery sign on MRI.

The differential diagnosis includes endometrial hyperplasiaendometrial carcinoma.

The pedicle artery sign on transvaginal color Doppler sonography has a sensitivity of 86.67%, an accuracy of 86.67%, a positive predictive value of 100%, and no false positive. It improves the specificity for the diagnosis of endometrial polyps 1.
