[Cytomegalovirus pneumonitis in immunocompetent adults: report of a case]. / Neumonitis por citomegalovirus en pacientes adultos inmunocompetentes: a propósito de un caso.

Cytomegalovirus produces congenital and acquired infections most of them asymptomatic. The percentage of clinical cases with visceral affection increases in patients suffering from a deficiency cellular immunity, showing the great importance of this defensive system in the control of the infection. This case presents an infection by Cytomegalovirus with visceral affection in an immunocompetent adult host. This is a mean duration of fever as the only symptom with lymphocytosis, biochemical hepatic changes and an interstitial pulmonary radiologic image. We think this case is a matter of considerable interest because it is a challenge in the study of the pathogenic mechanisms of this infection.
