Cerebral Venous Thrombosis in Acute Lymphoblastic Leukemia with Severe COVID-19: a Case Report

Area of Science:

• Hematology
• Infectious Diseases
• Neurology

Background:

• Coronavirus disease 2019 (COVID-19), caused by SARS-CoV-2, presents significant health challenges, including an increased risk of thromboembolism.
• Thromboembolic events contribute to COVID-19-related mortality and morbidity, with evolving understanding of mechanisms and at-risk populations.

Purpose of the Study:

• To present a case of a young patient with acute lymphoblastic leukemia (ALL) who developed severe COVID-19 and subsequently experienced cerebral venous sinus thrombosis (CVT).
• To discuss the implications for identifying high-risk groups and developing guidelines for thromboprophylaxis in similar complex cases.

Main Methods:

• A case report detailing the clinical course of a young ALL patient treated for severe COVID-19 pneumonia.
• Diagnostic imaging including contrast-enhanced magnetic resonance imaging (CEMRI) and magnetic resonance venography (MRV) of the brain.
• Management involved therapeutic anticoagulation and cerebral decongestants, transitioning to oral anticoagulation therapy.

Main Results:

• The patient, initially diagnosed with ALL and treated with chemotherapy, developed severe COVID-19 pneumonia.
• Following recovery from COVID-19, the patient was diagnosed with CVT with hemorrhagic parenchymal changes.
• Successful management with anticoagulation and supportive care was achieved.

Conclusions:

• This case emphasizes the complex interplay between hematological malignancies, chemotherapy, COVID-19, and the risk of cerebral venous sinus thrombosis.
• There is a critical need to identify specific patient groups at high risk for thromboembolic complications and to establish clear guidelines for extended thromboprophylaxis.
