ICD-10: M12.251

Villonodular synovitis (pigmented), particularly in the context of the ICD-10 code M12.251, is a rare condition characterized by the proliferation of synovial tissue, which can lead to joint swelling, pain, and limited mobility. Below is a detailed clinical description and relevant information regarding this condition.

Clinical Description

Definition

Villonodular synovitis (pigmented) is a benign but locally aggressive condition that primarily affects the synovial membrane of joints, tendons, and bursae. The term "pigmented" refers to the presence of hemosiderin deposits, which are indicative of previous bleeding within the joint space. This condition is most commonly found in the knee but can also occur in other joints, including the hip.

Symptoms

Patients with villonodular synovitis may experience a variety of symptoms, including:
- Joint Pain: Often described as a dull ache, which can become more intense with activity.
- Swelling: The affected joint may appear swollen due to the accumulation of synovial fluid and tissue proliferation.
- Limited Range of Motion: Patients may find it difficult to move the joint fully due to pain and swelling.
- Joint Stiffness: Stiffness can occur, particularly after periods of inactivity.

Diagnosis

Diagnosis typically involves a combination of clinical evaluation and imaging studies. Key diagnostic methods include:
- MRI: Magnetic resonance imaging is the preferred method for visualizing the extent of synovial proliferation and any associated joint effusion.
- Ultrasound: This can be used to assess the joint and guide potential aspirations or biopsies.
- Histological Examination: A biopsy may be performed to confirm the diagnosis, revealing characteristic features such as synovial hyperplasia and hemosiderin deposits.

Treatment

Management of villonodular synovitis often involves:
