Cytomegalovirus as precipitating factor of acute bacterial sinusitis in an immunocompetent patient. A case report.

The authors report the first case of cytomegalovirus (CMV) isolated from the maxillary sinus of an immunocompetent patient with acute bacterial sinusitis. CMV has not been previously reported in the maxillary sinus of immunocompetent patients. The authors' hypothesis is that CMV can act as a precipitating factor for acute bacterial sinusitis.
