Atypical Orbital Cellulitis Caused by Methicillin-Resistant Staphylococcus aureus: Two Cases

Purpose: To report two cases of orbital methicillin-resistant Staphylococcus aureus (MRSA) cellulitis. Summary: We report two cases of orbital methicillin-resistant Staphylococcus aureus (MRSA) cellulitis with the unusual origins of nosocomial MRSA infection after facial osmetic procedures (forehead fat graft and canthoplasty) and community-acquired MRSA infection after trauma. Orbital swelling was patients chief complaint and rapid necrotic change of fat tissue or diffuse soft tissue infiltration was presented. Intraoperative wound cultures grew MRSA in both patents. After treatment of systemic antibiotics all symptoms were gradually improved. Conclusion: Severe and rapid necrotic change in the soft tissue, including orbital fat and levator muscle, can be an important sign of MRSA infection.
