Doctors are being urged to be on the alert for cerebral thrombosis in relation to even mild cases of COVID-19, after a teenager was found to have an extensive clot weeks following the illness. 

The 18-year-old had experienced persistent headaches after recovering from COVID-19, the UK doctors write in BMJ Case Reports. 

He was eventually diagnosed with extensive cerebral venous sinus thrombosis (CVST) despite having no other thrombotic risk factors.

The cerebral thromobosis was considered a sequela of his earlier COVID-19 illness.
