Infiltrative and interstitial lung disease in the elderly patient

Diagnosis usually requires a systematic approach and often requires lung biopsy. Treatment typically involves the use of immunosuppressive dosages of corticosteroids or cytotoxic agents. The use of these medications in the elderly demands meticulous, close follow-up because side-effects can be substantial.
