4. Diagnóstico diferencial de la fibrosis pulmonar idiopática

Abstract

For the accurate diagnosis of idiopathic pulmonary fibrosis (IPF), the presence of a definitive tomographic pattern of usual interstitial pneumonia (UIP) is of vital importance, in an appropriate clinical context. Targeted interrogation, the use of valid questionnaires, an acute rheumatologic evaluation and complementary examinations are important to rule out secondary causes such as hypersensitivity pneumonitis (HP), connective tissue diseases (CTD), drug toxicity and some pneumoconiosis that can mimic the radiological pattern and often hinder a clear diagnosis of IPF.
