Question

Which of the following is a false statement with respect to differentiating the appearance of a leiomyosarcoma from that of a leiomyoma?

They may be single or multiple.
Serial ultrasounds over six months will demonstrate a large size difference in a leiomyosarcoma whereas a leiomyoma will likely be unchanged in size.
Both can demonstrate a heterogeneous hypoechoic appearance with shadowing.
Only leiomyosarcoma will be singular.

Answer 1

A leiomyosarcoma and a leiomyoma can have differentiating features in terms of size change over time, but both can be single or multiple and can demonstrate a hypoechoic and heterogeneous appearance with shadowing.

Step-by-step explanation:

A leiomyoma is a benign tumor that arises from smooth muscle cells in the uterus, while a leiomyosarcoma is a malignant tumor that also originates from smooth muscle cells in the uterus. The false statement in the given options is that 'Only leiomyosarcoma will be singular.' Both leiomyoma and leiomyosarcoma can be either single or multiple.

Serial ultrasounds over six months can help differentiate between a leiomyosarcoma and a leiomyoma. While a leiomyosarcoma may demonstrate a significant difference in size over time, a leiomyoma will typically remain unchanged in size. Both tumors can appear hypoechoic and heterogeneous with shadowing, making it important to consider other diagnostic methods for accurate identification.
