Sinusitis

Abstract

Article abstract—In 17 cases of sinusitis-induced subdural empyema, all but 5 occurred in boys or men aged 13 to 33 years. Clinical features were headaches and fever (14 patients), nuchal rigidity (10)., and seizures (8). Seven patients had periorbital cellulitis, and 15 had radiographic clouding of at least one sinus. Only five patients had a history of sinusitis. CT identified the empyema accurately in seven patients but failed in two patients who developed subdural empyema while being treated for sinusitis-induced cerebritis. Ten patients had specific bacteriologic etiologies determined by culture of empyema, blood, or sinuses.
