Yes, cerebral venous sinus thrombosis, exceedingly rare condition in the general population. It can cause permanent neurological disability and death if not diagnosed and treated.
Cerebral venous sinus thrombosis presents with nonspecific symptoms (eg headaches). It can only be diagnosed with cerebral imaging of specific modalities (CT or MR brain venogram, expensive and specialised tests). From speaking to colleagues in the UK, their hospital system is quite overwhelmed and doctors are repurposed outside their field (eg surgeons looking after internal medicine patients). It is quite possible in the throes of a pandemic to be underestimating the incidence of this condition in the UK.
