Knee MRI Cases

<div>History:&#160;This 27-year-old male presents with pain and swelling in the anterior left knee.MOST LIKELY DIAGNOSIS: Rheumatoid arthritis&#160;Using the diagnostic web viewer, we have provided images that assist in telling our clinical story. Areas of significance are indicated below.<figure class="wp-block-image"><img src="https://process.fs.teachablecdn.com/ADNupMnWyR7kCWRvm76Laz/resize=width:750/https://www.filepicker.io/api/file/SXmrQF9oTq8139fla2rO" alt=""></figure>CLINICAL CONSIDERATIONS:This 27-year-old male presents with pain and swelling in the anterior left knee. The symptoms began eight months prior. There was no known injury or previous surgery.Have a look at images 1 through 3, and see if anything stands out. Do not be distracted by the obvious finding.The images show normal menisci, ligaments, and tendons. There is a large joint effusion. A normal plica is visible, which is not thickened.If you look closely in the posterior aspect of the suprapatellar joint capsule, there is frond-like synovitis or pannus (images 1 through 3, green arrows). Therefore, the most likely diagnosis is rheumatoid arthritis or seronegative arthropathy. In certain continents, Lyme disease would be a differential. Gout is more common in older patients.It is important to correlate the findings, and not be distracted by prominent plica, which would not cause the degree of joint effusion.</div>
