COVID-19 as a trigger of cerebral venous sinus thrombosis in a patient with autoimmune hyperthyroidism: a case report.

Egypt J Neurol Psychiatr Neurosurg 2022 11;58(1):40. Epub 2022 Apr 11.

Faculty of Medicine, Pelita Harapan University, Jl. Boulevard Jend. Sudirman No. 20, Lippo Karawaci, Tangerang, Banten 15810 Indonesia.

Background: Cerebral venous sinus thrombosis (CVST) composes an uncommon subtype of stroke caused by thrombotic occlusion of the cerebral venous system and tends to occur in hypercoagulable states. Albeit exceedingly rare, autoimmune hyperthyroidism and COVID-19 has been implicated as rare risk factors for CVST. As both conditions are capable of inducing degrees of inflammation and hypercoagulability, we postulate that COVID-19 could trigger CVST by superimposing endotheliitis and inflammation on the hypercoagulable and hypofibrinolytic state of hyperthyroidism.

Diabetic ketoacidosis, cerebral venous sinus thrombosis and fulminant cerebral oedema in COVID-19 infection complicated by infection.

BMJ Case Rep 2022 Apr 4;15(4). Epub 2022 Apr 4.

Pulmonary and Critical Care Medicine, Mayo Clinic, Rochester, Minnesota, USA.

We present an unusual case of a woman in her 30s who was admitted for diabetic ketoacidosis (DKA) in the setting of newly diagnosed but late COVID-19 infection with associated infection.

Factors Contributing to Attenuation of Cerebral Venous Sinus in Brain Noncontrast Computed Tomography Scan.

Indian J Radiol Imaging 2021 Oct 10;31(4):882-887. Epub 2022 Jan 10.

Neuroscience Research Center, Department of Neurology, Poursina Hospital, School of Medicine, Guilan University of Medical Sciences, Rasht, Iran.
