Do lipoma and liposarcoma look the same on ultrasound?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

I just had an ultrasound, which diagnosed a small 0.8-inch lipoma on my belly. The sonographer advised that there are no worrying features and the findings are consistent with a lipoma.

My question is:

Do lipomas and liposarcomas look the same on ultrasound, or do they have different characteristics?

Please help,

Thank you.

Hello,

Welcome to icliniq.com.

I have gone through your query and understand your concern.

I am happy to provide a consultation for you. As you asked, I am giving a detailed answer about lipoma and liposarcoma.

Lipomas are noncancerous lumps that form in fat cells just beneath the skin or in soft tissues such as muscles, fat, tendons, and nerves. They are typically painless and move easily when touched. While lipomas can appear anywhere on the body, they are most commonly found on the arms, back, neck, and shoulders.

Lipomas usually do not require treatment and are often removed surgically for cosmetic reasons. They are very common and most often occur in people between the ages of 40 and 60.

Liposarcomas, or lipomatous tumors, also form in fat cells but are a type of soft tissue cancer. They can occur in any part of the body but are most commonly found in the abdomen, legs, or arms.

Liposarcomas are usually painless and slow-growing, although they may sometimes grow quickly and press on surrounding tissues or organs. Treatment typically involves surgery, radiation, and chemotherapy.

An ultrasound can help differentiate between a lipoma and a liposarcoma. While both may appear as soft tissue masses, liposarcomas often show different features such as an irregular shape, increased blood flow, and invasion into nearby tissues, which can be identified on imaging.

I hope I have answered your question.

Let me know if I can assist you further.

Thank you.

Patient's Query

Hello doctor,

Thank you for your reply.

My ultrasound showed no vascularity, a smooth encapsulated shape, and tissue consistent with the surrounding soft tissues.

Can these findings reassure me?

Please help.
