Infectious mononucleosis-like syndrome and gastrointestinal disorders in acute acquired cytomegalovirus infection.

Acute acquired cytomegalovirus (CMV) infection occurring in an 18-year-old Brazilian woman is reported. She presented with high fever, diarrhoea, colicky abdominal pain, vomiting, arthralgia and asthenia. CMV IgG Ab (151) and CMV IgM Ab were positive. ELISA was confirmed by immunofluorescence. The patient received symptomatic treatment and recovered fully. It is unusual to have features of infectious mononucleosis-like syndrome and gastrointestinal disorders in the same patient.
