Cerebral deep venous thrombosis and COVID-19: case report

Herein, the authors present the case of a 54-year-old male diagnosed with coronavirus disease 2019 (COVID-19) dur-ing a screening test. The patient was asked to self-isolate at home and report with any exacerbations of symptoms. He presented later with pneumonia complicated by encephalopathy at days 14 and 15 from initial diagnosis, respectively. MRI of the brain showed bithalamic and gangliocapsular FLAIR signal abnormality with mild right-sided thalamic and periventricular diffusion restriction. A CT venogram was obtained given the distribution of edema and demonstrated deep venous thrombosis involving the bilateral internal cerebral veins and the vein of Galen. CSF workup was negative for encephalitis, as the COVID-19 polymerase chain reaction (PCR) test and bacterial cultures were negative. A complete hypercoagulable workup was negative, and the venous thrombosis was attributed to a hypercoagulable state induced by COVID-19. The mental decline was attributed to bithalamic and gangliocapsular venous infarction secondary to deep venous thrombosis. Unfortunately, the patient's condition continued to decline, and care was withdrawn.

Automated summary

A 54-year-old male diagnosed with COVID-19 developed pneumonia and encephalopathy, with brain MRI showing abnormalities. Despite negative results in CSF and hypercoagulable workup, deep venous thrombosis was attributed to COVID-19, leading to the patient's deteriorating condition and withdrawal of care.
