An alternative name for cryptogenic fibrosing alveolitis (CFA, or idiopathic pulmonary fibrosis, IPF), used by lung pathologists to classify the different cellular types of the disease. The most common cellular pattern seen on CT scanning is usual interstitial pneumonitis (UIP). Use of the latter abbreviation is increasing in clinical contexts: the diagnosis CFA/UIP or just UIP now often appears in hospital notes and discharge letters. A differing cellular pattern with cellular infiltrate is seen in patients with nonspecific interstitial pneumonitis (NSIP).
