"Septic cavernous sinus thrombosis occurs due to embolisation of bacteria which trigger thrombosis that becomes trapped within the cavernous sinus. The subsequent reduction in venous drainage results in facial and periorbital oedema, ptosis, proptosis, chemosis, painful eye movements, papilloedema, retinal venous distension, and loss of vision 7."
"As the dural venous and cavernous systems are valveless, communication between dural sinuses and cerebral and emissary veins can lead to meningitis, dural empyema or cerebral abscess 7. Propagation of infection via the internal jugular vein can result in septic pulmonary emboli, pulmonary abscess, pneumonia or empyema 7. Compression of the internal carotid artery and pituitary gland may result in stroke and hypopituitarism respectively 7."
