Presentamos 2 pacientes con una enfermedad pulmonar intersticial difusa atribuida a dos formas distintas de presentación de una neumonitis por inhalación de isocianatos. Una de forma aguda o accidental y otra ocupacional, tras una exposición más prolongada. En ambos casos, los hallazgos clínicos, radiológicos, funcionales y del BAL son similares a los observados en las neumonitis por hipersensibilidad a agentes orgánicos.
We present two patients with diffuse interstitial lung disease attributed to two different forms of presentation of pneumonitis due to inhalation of isocyanates. The first case was acute and accidental and the second was due to longer workplace exposure. In both cases, clinical, radiological and lung function findings as well as results of bronchoalveolar lavage were similar to those of hypersensitivity pneumonitis triggered by organic agents.
