A Cause of Bicytopenia in Infancy: CMV

Bicytopenia is frequently observed in the pediatric population as a result of transient bone marrow suppression, which may occur following vaccination or as a consequence of viral infections, including influenza, Epstein-Barr virus (EBV), and cytomegalovirus (CMV). Symptoms of CMV infection, one of these agents, vary according to age and host immune competence. Although it is usually asymptomatic in healthy children, it can cause various infectious clinical presentations. In immunocompromised patients, it may cause pneumonia, retinitis, hepatitis, fever, thrombocytopenia and leukopenia. Here, we present a 4-month-old girl who was investigated for bicytopenia and subsequently diagnosed with CMV infection.
