Definition of CMV esophagitis
Cytomegalovirus (CMV) esophagitis is a viral infection of the esophagus, the muscular tube through which food travels from the mouth to the stomach.
Causes, incidence, and risk factors
CMV esophagitis is caused by the cytomegalovirus (CMV).
Treatment involves antiviral medications that are given through a vein (intravenously), such as ganciclovir or foscarnet. In some cases, patients are given an antiviral medicine called valganciclovir, which is taken by mouth.
Esophagitis can usually be treated effectively. The outcome depends on the immune system problem that makes the person more likely to get the infection.
