What is synovial hypertrophy knee?
Inflammation of the synovium leads to hypertrophy (thickened tissue), increased vascularity (blood flow to the area), and increased fluid production, resulting in joint pain, tenderness, and swelling.
Does synovial fluid show up in an MRI?
Magnetic resonance imaging (MRI) allows unparalleled assessment of all joint structures and associated pathology. It has emerged as a powerful tool, which enables not only detection of synovitis and effusion, but also allows quantification, detailed characterization and noninvasive monitoring of synovial processes.
What causes synovial hypertrophy?
Synovitis causes In an active, healthy person, the most common cause of synovitis is overuse of the joint, for example in athletes or people whose jobs involve repetitive stress movement such as lifting or squatting. However, synovitis is also common in people who have some form of inflammatory arthritis.
Does normal synovium enhance on MRI?
The normal synovium does not enhance [1,2], and therefore remains invisible. Small joint effusions may be seen in several normal joints using MRI, and these small effusions will enhance intensely on rrweighted MR images [1].
Do you need surgery for synovitis?
A synovectomy is a surgical procedure used to treat synovitis and some other conditions that affect the synovium, a thin membrane that lines the inside of certain joints (called “synovial joints”), such as your knee, shoulder or elbow. In a synovectomy procedure, much of the synovium is removed.
Does synovitis ever go away?
Synovitis can go away on its own, but if the symptoms linger, treatment may be necessary. Treatment for synovitis depends on the underlying cause. In most cases, treatments are geared to decrease inflammation, lessen swelling, and manage pain.
Does an MRI show up inflammation?
MRI is an imaging method that is very sensitive in detecting inflammation and also bone erosions. This makes MRI an interesting tool to measure the course of the disease in randomised clinical trials and this suggests that MRI may also be useful in the diagnostic process.
Can contrast MRI show inflammation?
MRI allows to assess the soft tissue and bone marrow involvement in case of inflammation and/or infection. MRI is capable of detecting more inflammatory lesions and erosions than US, X-ray, or CT.
What does MRI synovitis look like?
On MRI, the most common finding is synovitis that appears hypointense on T1WI, hyperintense on T2WI, and marked enhancement following intravenous (IV) contrast administration (Figure 4a, b, 5a, b). In some cases, the meniscus may be smaller in size because of synovial hypertrophy.
What is synovial hypertrophy in the unaffected knee joint?
DISCUSSION. The characteristic synovial hypertrophy in the unaffected knee joint was also found in this case, and this type of synovial hypertrophy can be found in various infectious diseases and primary synovial diseases such as RA, degenerative arthritis, and pigmented villonodular synovitis (PVNS).
What is synovial hypertrophy and PVNS?
Synovial hypertrophy such as exudative joint or papillary proliferation in the synovial joint can be observed. Among these, PVNS is a proliferating disease, which originates from synovial joints, synovial cysts, and synovial sheath. It occurs in all age groups, and the most frequently affected joint is the knee.
What is the most reliable diagnostic feature of synovial thickening?
The most reliable diagnostic feature is the deposition of hemosiderin-laden macrophages viewed on T1- and T2-weighted images and on echo gradient imaging. As seen in Fig. 10.2, the synovial thickening can produce diffuse low-signal-intensity masses.
Can MR arthrography detect intra-articular bodies in the knee?
However, in the knee, intra-articular bodies are often large, and usually there is enough joint fluid present. Thus, MR arthrography in the knee for the detection of intra-articular bodies is not recommended as a standard procedure, but can be helpful in cases where intra-articular bodies are suspected but cannot be otherwise detected.
