Cytomegalovirus pneumonia in a patient with breast cancer on chemotherapy:Case report and review of the literature

Cytomegalovirus (CMV) pneumonia in the setting of nontransplantation patien ts is a rarity. We present a case of CMV pneumonitis in a woman with stage IV breast cancer, with brain metastases, receiving both chemotherapy and sy stemic corticosteroids. A review of the literature reveals this as a unique case. Potential viral etiologies should therefore be considered in cancer patients with pneumonia receiving non-transplantation chemotherapy-regimens , particularly if steroids are a component of their therapy.
