Background: Subscapular abscess is a rare condition usually secondary to immunocompromised state and recent infection. Staphylococcus aureus (S. aureus) is the most common etiologic agent. To the best of our knowledge, we present the first case of a patient with a frozen shoulder performing manual therapy, which resulted in an Escherichia coli subscapular abscess.Case presentation: A 72-year-old male was referred from the respiratory department with pain and a limited range of motion in the left shoulder. He complained that the pain was exacerbated with popping sound during manual therapy for frozen shoulder two weeks ago. Magnetic resonance imaging revealed a large intramuscular complicated fluid collection at the level of the subscapularis muscle 10.0 × 5.2 × 11 cm in size, and a bloody but turbid pus-like discharge was observed upon aspiration. He underwent urgent surgical drainage. The cultures from the abscess fluid revealed extended-spectrum beta-lactamases (-) E. coli. After 4 weeks of Ceftazidime intravenous treatment, symptoms of the patient had improved. Conclusions: This case highlights the risks of aggressive manual therapy in severe frozen shoulder. It also presents a clinical scenario in which practitioners of manual therapy in frozen shoulder should be aware of the risk of subscapular abscess in patients undergoing recent infection therapy |
