Question 1

What are the ultrasound features of a leiomyoma?

Answer 1

The myomatous uterus is typically enlarged and its outline may be irregular or lobular. The most common appearance of a leiomyoma is that of a well-marginated, hypoechoic, rounded and/or oval mass within the uterine body. Depending on the proportion of smooth muscle, fibrosis and degeneration present within the myoma, the appearance may range from hypoechoic to echogenic, homogenous to heterogeneous, with or without acoustic shadowing ( Fig 54.11 ). Calcification when present appears as shadowing echogenic foci.
