Cytomegalovirus is the most frequent causative agent of perinatal infection and a major cause of acquired viral infections. This case report aims to show the broad clinical spectrum of the presentation of cytomegalovirus infection. The correct classification of congenital or acquired infection and its prompt treatment can prevent complications and sequelae in severe cases. We report the case of an infant with acquired cytomegalovirus infection, which presented an unusual feature of cerebral hemorrhage. The patient was treated with ganciclovir, with a favorable evolution of the clinical symptoms. Cytomegalovirus infection is common in children, both in its congenital and acquired forms. Acquired infection, as portrayed in this case, is mainly characterized by hematological compromise given by the marked thrombocytopenia, which may rarely result in cases of bleeding in the central nervous system. In this patient, no important clinical implications occurred. In addition, most of the acquired infections are self-limited and require no treatment.
