Orbital cellulitis with periorbital abscess secondary to methicillin-resistant Staphylococcus aureus (MRSA) sepsis in an immunocompetent neonate.

This article advocates the need for early incision and drainage of periorbital abscesses. We report a case of a 1.5-month-old neonate with orbital cellulitis and periorbital abscess, which had rapidly developed over a period of 3 days. Treatment history revealed methicillin-resistant Staphylococcus aureus sepsis treated with intravenous vancomycin, and incision and drainage of abscesses at multiple sites (left parotid region, upper and lower limbs). A small swelling noted on the left temporal region on discharge from the hospital was treated with oral cotrimoxazole. However, it spread rapidly to involve the periorbital tissue and the bones of the orbital walls to form a periorbital abscess and orbital cellulitis.
