COVID-19 complicated by immune thrombocytopaenic purpura and internal jugular vein thrombosis

A 61-year-old woman who had tested positive for COVID-19 in the community 5 days prior to admission presented with new onset severe headache and mild shortness of breath. She had an acute reduction in her platelet counts from 153×10⁹/L to 5×10⁹/L. She was diagnosed with immune thrombocytopenia purpura and after treatment with intravenous immunoglobulin, her platelet count increased to 15×10⁹/L. Due to nonresolving headache, she had a magnetic resonance venogram, which showed bilateral internal jugular vein thrombosis. She was discharged from hospital and followed up in Haematology and Neurology clinics. Her platelet count returned to normal range 7 days later. She was commenced on anticoagulation for thrombosis.
