Abstract
BACKGROUND: Pyomyositis, traditionally prevalent in tropical regions, is increasingly diagnosed in temperate climates and among healthy individuals. This condition's nonspecific symptoms often complicate its diagnosis, necessitating advanced imaging for precise identification. This case underscores the novel occurrence of pyomyositis in a healthy individual from a temperate region and highlights the aggressive nature of methicillin-resistant Staphylococcus aureus. CASE PRESENTATION: We report a case of a 32-year-old healthy Pakistani male who presented with localized swelling in the right deltoid and forearm, accompanied by high-grade fever and systemic symptoms. Imaging revealed extensive abscess formation, and microbiological cultures identified methicillin-resistant Staphylococcus aureus as the causative agent. Initial treatment with linezolid showed partial improvement; however, recurrent abscesses required surgical drainage. Following this combined treatment approach, the patient showed significant recovery. CONCLUSION: This case emphasizes the importance of prompt diagnosis and intervention in pyomyositis, even in otherwise healthy individuals. It supports the use of integrated therapeutic approaches, including antimicrobial therapy and surgical intervention, for managing complex bacterial infections.
