A case of acute periorbital necrotizing fasciitis

A case of necrotizing fasciitis of the orbit secondary to Aspergillus fumigatus and mixed flora

A 79-year-old female presented to the emergency department for sudden-onset ocular pain, edema, and erythema around her left eye. She also had a left-sided migraine and frontal fullness for 2 weeks. She had attentive care for the diagnosis of orbital cellulitis and prompt recognition of necrotizing fasciitis. Wound cultures were positive for over 5 strains of bacteria in addition to Aspergillus. In a combined effort by our institution's Ophthalmology and Otolaryngology departments, the patient was successfully treated with debridement, porcine bladder matrix, antibiotics, and antifungals. The authors describe the first reported case of eyelid and periorbital necrotizing fasciitis, caused by mixed flora and Aspergillus fumigatus, that showed promising wound healing with the outlined treatment paradigm.

Pathophysiological Considerations in Periorbital Necrotizing Fasciitis: A Case Report

BACKGROUND

Periorbital necrotizing fasciitis (PNF) is a rare complication of bacterial infection, associated with irreversible inflammatory destruction of soft tissues like subcutaneous tissue and superficial fascia. PNF can cause visual loss, septic shock and death within hours to days. Since the infection progresses rapidly from a local disease to septic shock, prompt identification and decisive interventions are mandatory.

AIM

Considering pathophysiology, differential diagnosis, and treatment options, we report a case of PNF and its outcome.

METHODS

A 69 years old male with febrile periorbital swelling had been diagnosed with bilateral PNF, caused by dual infection with Streptococcus pyogenes (S. pyogenes) and Staphylococcus aureus (S. aureus) based on conjunctival swabs.

RESULTS

The superantigens produced by S. pyogenes have been identified as key to the rapid dissemination of infection and severity of systemic manifestations.

CONCLUSION

A combination of intravenous antibiotics and regular surgical debridements resulted in a beneficial outcome in our patient.
