A 40-year-old man presented with severe headache and pain and swelling of right eye for four days and consulted with an eye specialist who prescribed him analgesic and steroid, but he did not get any relief. The patient was hospitalized and treated at a medical college hospital for COVID-19 moderate illness, which was identified clinically and confirmed by RT-PCR positive and HRCT of the chest. He improved immensely without complications and was discharged from the hospital on 28/4/2021 following a 14-day hospital stay on rivaroxamine 10 mg daily, vitamin D, vitamin C, and zinc. The cavernous sinus (CS) is a pair of cerebral dural venous sinuses found in the middle cranial fossa on each side of the sellaturcica. The cavernous sinus contains the third, fourth, and sixth cranial nerves, as well as the ophthalmic and maxillary divisions of the fifth cranial nerve and the internal carotid artery with its surrounding sympathetic plexus. CST related with COVID-19 is becoming more common, however therapy is problematic since the appropriate anticoagulant and length of therapy are unknown. We are now treating the patient with subcutaneous low molecular heparin.
