What Is a Lytic Lesion?

An osteolytic lesion is a softened section of a patient's bone formed as a symptom of specific diseases, including breast cancer and multiple myeloma. This softened area appears as a hole on X-ray scans due to decreased bone density, although many other diseases are associated with this symptom.

What is the meaning of lytic lesion?

What are Lytic Lesions? Also known as bone lesions or osteolytic lesions, lytic lesions are spots of bone damage that result from cancerous plasma cells building up in your bone marrow. Your bones can't break down and regrow (your doctor may call this remodel) as they should.

Are lytic lesions always cancerous?

They are benign, asymptomatic tumors with a well-defined sclerotic margin. They are usually juxtacortical in location and typically occur in the metaphysis of long bones, and are most common in the under 30 age group. When the lesion is smaller than 2 cm, it is called a fibrous cortical defect (FCD).
