Title: Imaging of Rheumatic Diseases: Magnetic Resonance Imaging, Computed Tomography and X-ray

Session Type: Abstract Submissions (ACR)

Background/Purpose:

Patients suffering from acute sarcoidosis frequently present with bilateral painfull swelling of the ankles, establishing ankle arthritis as a hallmark of Löfgren’s syndrome. Standardized high resolution musculoskeletal ultrasound (MUS) including power Doppler has been utilized to further characterize the nature of the ankle swelling in patients presenting with Löfgren’s syndrome.

Methods:

Ankle joints of 36 consecutive patients suffering from Löfgren’s syndrom were investigated by high resolution MUS using B- and power Doppler mode. Presence of effusion / synovitis and tenosynovitis has been determined, and hyperperfusion was scored in a semiquantitative fashion (grade 0-3).

Results:

The majority of patients (26/36; 72,2%)  did not present characteristic arthrosonographic findings of an acute arthritis (distension of the capsule and hyperperfusion). Ankle joint effusion was only observed in 9 of the 36 patients (25%). Remarkably, 88,8% of these patients had an ankle effusion grade I and only 11,1% presented an effusion grade II. Instead, an extensive subcutaneous edema indicating periarthritis was detected in 23 of 26 patients (88,4%). In addition, tenosynovitis could be visualized in 14 patients (38,8%).

Conclusion:

Utilizing MUS including power Doppler, the present results clearly demonstrate that ankle swelling in patients suffering from Löfgren´s syndrome is predominantely due to periaticular soft tissue swelling and tenosynovitis. In contrast, distinct articular synovitis is rare and if present only of mild degree without relevant power Doppler activity.

All abstracts accepted to ACR Convergence are under media embargo once the ACR has notified presenters of their abstract’s acceptance. They may be presented at other meetings or published as manuscripts after this time but should not be discussed in non-scholarly venues or outlets. The following embargo policies are strictly enforced by the ACR.

Accepted abstracts are made available to the public online in advance of the meeting and are published in a special online supplement of our scientific journal, Arthritis & Rheumatology. Information contained in those abstracts may not be released until the abstracts appear online. In an exception to the media embargo, academic institutions, private organizations, and companies with products whose value may be influenced by information contained in an abstract may issue a press release to coincide with the availability of an ACR abstract on the ACR website. However, the ACR continues to require that information that goes beyond that contained in the abstract (e.g., discussion of the abstract done as part of editorial news coverage) is under media embargo until 10:00 AM ET on November 14, 2024. Journalists with access to embargoed information cannot release articles or editorial news coverage before this time. Editorial news coverage is considered original articles/videos developed by employed journalists to report facts, commentary, and subject matter expert quotes in a narrative form using a variety of sources (e.g., research, announcements, press releases, events, etc.).

Violation of this policy may result in the abstract being withdrawn from the meeting and other measures deemed appropriate. Authors are responsible for notifying colleagues, institutions, communications firms, and all other stakeholders related to the development or promotion of the abstract about this policy. If you have questions about the ACR abstract embargo policy, please contact ACR abstracts staff at [email protected].
