Case in brief
A man in his 50s presented with visual loss, altered consciousness, and shock due to septic cavernous sinus thrombosis from odontogenic maxillary sinusitis, complicated by non-aneurysmal subarachnoid hemorrhage. CT imaging showed SAH near the left Sylvian fissure and extensive thrombosis. Despite aggressive treatment, he developed a hemorrhagic venous infarction and died from cerebral herniation.
What made this case unusual
The case underscores the pathogenic potential of Group C Streptococcus, isolated from blood cultures and purulent material during tooth extraction, linking it to severe neurological complications.
Diagnostic / clinical pearl
Clinicians should consider septic cerebral venous thrombosis as a potential cause of subarachnoid hemorrhage, especially in cases of odontogenic infections.
Why it matters
This case emphasizes the need for awareness of the serious complications associated with odontogenic infections and the role of Group C Streptococcus in such scenarios.
