The article describes a clinical case concerning a rare symptom complex developed as a result of toxic vascular thrombosis against the background of COVID-19 infection. The case concerns a 69-year-old man , after being infected with the COVID-19 neurovirulent strain, was diagnosed with septic thrombosis of the left transverse and sigmoid sinuses, as well as the left eyeball and maxillary arteries.

Oral inspection revealed extensive soft tissue necrosis on the corresponding half of the soft palate, where a demarcation line was later formed and the necrotic tissues were pulled out. Even after this, the necrotic area of the underlying bone tissue was exposed. The patient underwent complex treatment with the participation of a neurologist, an infectious disease specialist, an endocrinologist and a maxillofacial surgeon. The patient was discharged from the clinic in a stable condition and was advised on the need for further treatment in order to reconstruct the tissue deficit.
