Subscapular Abscess Caused by Panton-Valentine Leukocidin-Positive Staphylococcus aureus: An Atypical Presentation

الملخص EN

Subscapular abscess is an uncommon condition which requires early recognition followed by prompt surgical intervention.

We present a case of spontaneous subscapular abscess following blunt trauma to the shoulder in a patient with a history of recurrent superficial soft tissue infections, in which Panton-Valentine leukocidin-producing S.

aureus was identified as the infectious agent.

This strain due to its virulence can lead to fatal infections in otherwise healthy individuals; therefore, a high index of suspicion is needed to investigate with an MRI to rule out abscess formation in a patient with acute shoulder girdle pain and negative joint aspirate.

Urgent surgical intervention and targeted antimicrobial therapy against PVL-positive S.

aureus in accordance with microbiologist yield good outcomes.
