Radiology · Gynaecological imaging: uterine fibroid

Sample item

A 40-year-old woman with menorrhagia has a transvaginal ultrasound showing an enlarged uterus with a well-defined, rounded, hypoechoic mass in the myometrium causing edge shadowing. What is the most likely diagnosis?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

A. Leiomyoma (fibroid)

Fibroids are the commonest uterine tumours, appearing as well-circumscribed hypoechoic, whorled myometrial masses with edge shadowing, and on MRI they are of low T2 signal. Calcification and degeneration may alter the appearance.

Option by option

  • A. Leiomyoma (fibroid) (correct)

    Correct. A circumscribed hypoechoic myometrial mass is a fibroid.

  • B. Endometrial cancer

    Endometrial cancer thickens the endometrium.

  • C. Endometrial polyp

    An endometrial polyp lies within the endometrial cavity.

  • D. Adnexal teratoma

    A teratoma is an adnexal lesion, not myometrial.
