Shewanella algae Causing Pediatric Orbital Abscess With Leptomeningitis

Area of Science:

• Ophthalmology
• Infectious Diseases
• Neurosurgery

Background:

• Ocean swimming can expose individuals to diverse marine microorganisms.
• Bacterial infections of the orbit and sinuses can lead to severe complications.

Observation:

• A 13-year-old boy developed periorbital pain, swelling, and fever after swimming in the ocean.
• Rapid clinical deterioration occurred with subperiosteal and epidural abscesses, and leptomeningitis despite broad-spectrum antibiotics.

Findings:

• Surgical drainage and cultures revealed Shewanella algae and Escherichia coli as causative agents.
• This is the first reported case of orbital abscess and acute bacterial rhinosinusitis due to Shewanella algae.

Implications:

• Highlights Shewanella algae as a potential pathogen in severe orbital and intracranial infections.
• Emphasizes the importance of considering marine-associated pathogens in unexplained infections after water exposure.
• Underscores the critical role of prompt surgical intervention and tailored antibiotic therapy in managing such aggressive infections.
