Villonodular synovitis
Villonodular Synovitis
Villonodular synovitis (pronounced: vil-oh-nod-yuh-lar si-no-vi-tis) is a rare, benign condition that affects the synovium, or the lining of the joints. It is characterized by the overgrowth of the synovium, leading to the formation of nodules or villi.
Etymology
The term "villonodular synovitis" is derived from three words: "villi", "nodular", and "synovitis". "Villi" is a Latin term meaning "shaggy hair", referring to the villous appearance of the affected synovium. "Nodular" is derived from the Latin "nodulus", meaning "small knot", referring to the nodules that form in the synovium. "Synovitis" is a combination of the Greek words "synovia", meaning "joint fluid", and "-itis", a suffix used in medical terminology to denote inflammation.
Types
There are two types of villonodular synovitis: localized and diffuse.
- Localized Villonodular Synovitis (LVS) affects a specific area of the joint. It is often easier to treat because the overgrowth is confined to a specific area.
- Diffuse Villonodular Synovitis (DVS) affects the entire synovium. This form is more aggressive and can lead to joint damage and disability if not treated promptly.
Symptoms
Symptoms of villonodular synovitis can vary depending on the type and location of the condition. Common symptoms include joint pain, swelling, stiffness, and decreased range of motion. In some cases, a mass may be felt in the affected joint.
Diagnosis
Diagnosis of villonodular synovitis typically involves a combination of physical examination, medical history, and imaging tests such as MRI or X-ray. In some cases, a biopsy of the synovium may be required for definitive diagnosis.
Treatment
Treatment for villonodular synovitis typically involves surgery to remove the overgrown synovium. In some cases, medication may be used to manage symptoms or slow the progression of the disease. Physical therapy may also be recommended to improve joint function and mobility.
