[Immune thrombocytopenia preceded by asymptomatic COVID-19 infection].

Immune thrombocytopenia (ITP) may occur following a viral infection. We report the case of a 30-year-old woman with thrombocytopenia who was subsequently diagnosed with ITP. Although she was asymptomatic, chest computed tomography (CT) showed ground-glass opacities in the lower lung regions. The patient had a positive severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) real-time polymerase chain reaction (RT-PCR) test. She responded well to 400 mg/kg of intravenous immunoglobulin therapy. Coronavirus disease of 2019 or COVID-19 should be considered as a cause of ITP during the pandemic, and chest CT scans and RT-PCR tests should be performed in patients suspected of ITP.
