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

Area of Science:

• Neurology
• Infectious Diseases
• Hematology

Background:

• Chronic subdural hematoma (CSDH) typically affects elderly individuals and is usually supratentorial.
• COVID-19 infection has been linked to various neurological and hematological complications.
• Disseminated intravascular coagulation (DIC) is a serious condition that can arise secondary to infections.

Observation:

• A patient presented with both unilateral supratentorial and bilateral infratentorial CSDH.
• The patient had a history of COVID-19 infection and disseminated intravascular coagulation two months prior.
• No history of head trauma was reported preceding the CSDH onset.

Findings:

• This case demonstrates an unusual presentation of CSDH, involving both supratentorial and infratentorial compartments.
• The development of CSDH occurred in the absence of traumatic brain injury, suggesting an alternative etiology.
• Coagulopathy secondary to a prior COVID-19 infection and DIC is implicated as a potential cause.

Implications:

• Clinicians should consider CSDH as a potential delayed complication following COVID-19 infection, especially in patients with coagulopathy.
• Awareness of non-traumatic CSDH is crucial, particularly in the context of recent viral infections.
• Further research is warranted to elucidate the mechanisms linking COVID-19-associated coagulopathy to CSDH development.
