Septic cavernous sinus thrombosis in a patient with COVID-19.

ABSTRACT

The cavernous sinus is one of the dural venous sinuses which plays an important role in venous outflow from the brain and eye sockets and in the regulation of intracranial circulation. We report a case of septic cavernous sinus thrombosis in a female patient with COVID-19. The disease often results in alterations of blood rheology, thrombosis in different organs, and septic complications. This article aims to raise awareness of healthcare professionals about the characteristics of COVID-19 that might cause septic cavernous sinus thrombosis in patients with severe comorbidities. Laboratory testing revealed severe comorbidities, including diabetes mellitus and liver cirrhosis caused by hepatitis C. They manifested with an impaired protein production in the liver and coagulation disorders. Systemic effects of SARS-CoV-2 on the vascular endothelium aggravated preexisting coagulation disorders and led to hemorrhage into retrobulbar tissue and clinical signs of septic cavernous sinus thrombosis, including swelling of the eyelids, bilateral exophthalmos, and ophthalmoplegia, followed by necrosis of the facial skin.Copyright © 2022, Dynasty Publishing House.
