Orbital cellulitis or abscess may lead to thrombosis of the superior ophthalmic vein, which may lead to cavernous sinus thrombosis
Septic cavernous sinus thrombosis
complicated by narrowing of the internal carotid artery, subarachnoid abscess and multiple pulmonary septic emboli.
The prognosis and treatment of cavernous sinus thrombosis
Vascular lesions such as aneurysms and cavernous carotid fistula (Figure 24) and cavernous sinus thrombosis
or thrombophlebitis can be seen in the cavernous sinus region.
The distribution of those complications in Gallaghar's retrospective analysis was as follows: epidural abscess 23%, subdural empyema 18%, meningitis 18%, cerebral abscess 14%, superior sagittal sinus thrombosis 9%, cavernous sinus thrombosis
9%, and osteomyelitis 9%.
When cavernous sinus thrombosis
is present, eye pain, ophthalmoplegia, pupillary changes, and retinal hemorrhages may occur.
Left untreated, sinusitis can lead to meningitis, an infection of the brain that can lead to brain damage, or to a condition called cavernous sinus thrombosis
, a blood clot in veins around the sinuses that can affect the brain like a stroke.
A CT angiogram revealed the compromised left cavernous sinus and cavernous portion of the internal carotid artery and, subsequently, cavernous sinus thrombosis
, confirmed clinically and on imaging.
