[Chest diseases in elderly: role of imaging and clinical features].

Chest x-ray is the most useful examination in the elderly as community acquired pneumonia is very frequent in this high risk population. Technical details have to be considered due to the clinical status of elderly patients. Raising arms above the head may help in the radiographic diagnosis of pneumonia. Guidelines for good radiological practice indicate that a chest x-ray should be done in patients with acute respiratory illness and dementia. Clinical and biological findings of pneumonia may be misleading in the elderly and treatment should be instituted rapidly to avoid complications. Lung cancer of elderly patients has to be investigated and treated without consideration for age. Surgery should be done whenever the tumor is removable by lobectomy. Chemotherapy may be safe even in patients older than 80 with an acceptable quality of life.
