Idiopathic Pulmonary Fibrosis


Subpleural honeycombing and traction bronchiectasis are present on high-resolution CT in a patient with idiopathic pulmonary fibrosis (IPF). Findings inconsistent with IPF, such as nodules, are absent. These CT findings are virtually diagnostic of IPF if clinical findings are compatible.
