Subscapular bursitis as a rare manifestation of dermatomyositis: a case report

Rare Occurrence of Scapulothoracic and Ischiogluteal Bursitis Signifying Poorly Controlled Rheumatoid Arthritis

ABSTRACT

A 74-year-old man with poorly controlled seropositive rheumatoid arthritis was referred for 18F-FDG PET/CT for follow-up of lung cancer, which demonstrated intense FDG activity in atlantoaxial, sternoclavicular, glenohumeral, and hip joints consistent with active rheumatoid arthritis. There was also unexpected intense uptake at scapulothoracic, ischiogluteal, and trochanteric bursae signifying active bursitis.

Shoulder injury related to vaccine administration (SIRVA) following mRNA COVID-19 vaccination: Report of 2 cases of subacromial-subdeltoid bursitis

Shoulder pain has been reported as a common side-effect after COVID-19 vaccination particularly after administration of mRNA vaccines. Although it is usually mild and self-limiting, occasionally it can become more extensive causing severe pain and marked limited range of motion. Shoulder injury related to vaccine administration has been reported following injection of other routine vaccines. In this case report, we describe 2 cases of shoulder injury related to vaccine administration due to subacromial-subdeltoid bursitis after administration of mRNA COVID-19 vaccines.
