Chronic Subdural Hematoma, Caused by Disseminated Intravascular Coagulation and/or Anticoagulation Therapy, after COVID-19.

Abstract

Chronic subdural hematoma (CSDH) typically develops in the supratentorial region in elderly patients. We treated a case of unilateral supratentorial and bilateral infratentorial CSDH, whereby the patient had a coronavirus disease 2019 (COVID-19) infection combined with disseminated intravascular coagulation 2 months earlier. The patient had not experienced any head trauma before the onset of the CSDH. The postoperative course was uneventful, and the patient experienced no neurological deficit. We propose that we should be aware not only of acute ischemic or hemorrhagic diseases after COVID-19 infection but also of chronic subdural hematoma caused by coagulopathy after a COVID-19 infection.
