The diagnosis of CMV pneumonia can be suggested by chest radiography findings, but these findings cannot be used to differentiate between other common causes of pneumonia in immunocompromised hosts. A chest radiograph finding consistent with pneumonia and a BAL result that is CMV positive is a common method for diagnosis.

CT scan is more sensitive for the identification of infiltrate. It has been valuable in patients who present with hypoxia and no infiltrate visible on chest roentgenography.
