Abstract

Streptococcus pneumonia and Haemophilus influenzae account for more than 50% of bacterial acute sinusitis. Isolated sphenoid sinusitis is a rare disease with potentially devastating complications such as cranial nerve involvement, brain abscess, and meningitis. It occurs at an incidence of about 2.7% of all sinus infections. There have been no previous reported cases of unilateral sphenoid sinusitis presenting as septicaemia in an otherwise healthy young immunocompetent adult.
