Case contributed by Dr Shailaja Muniraju

Patient Data

Age: 30 years
Gender: Female
Annotated image

Annotated ultrasound image (transvaginal)

Well defined heterogeneous mass lesion replacing the anterior, mid and lower uterine body. This mass (red star) displaces the endometrium (white arrow) posteriorly.

MRI

Well defined intrauterine fibroid that appears T1 hypointense with T2 intermediate signal intensity. It is submucosal in location occupying the anterior, mid and lower uterine body. Broad interface with the endometrium, indenting and distorting the endometrial cavity. Intralesional cystic degenerative changes noted.

Case Discussion

MRI is the optimal imaging modality for fibroids. Radiologists must try to differentiate submucosal fibroids from endometrial polyps:

  • submucosal fibroids can displace or indent the endometrium
  • endometrial polyps arise within the endometrium and can cause distention of the endometrial cavity
