Síndrome febril prolongado y alteraciones hepáticas

cytomegalovirus (cmv) infection should be investigated in healthy patients who have flu-like symptoms consisting of fever, fatigue, unexplained increase of transaminases and peripheral lymphomonocytosis. these are relatively common symptoms so they may pass completely unnoticed or with few clinical manifestations, especially in immunocompetent patients. pharyngeal symptoms and swollen lymph nodes are less frequent than in mononucleosis infection caused by epstein-barr virus. we report a case of a patient with no risk factors who presented with persistent fever and liver alterations, which resolved spontaneously and with serological findings compatible with a recent cmv infection.
