2014;14 Suppl 1: S2. Riha, E.E. Human lung disease due to an inability to produce SP-B was the first recognized genetic cause of surfactant dysfunction. Geographic variability means there are some areas of advanced scarring while other areas are completely normal. h�b```�b�# cb�w�1h30R���_pǜ[�맥� � �P�a`���$@jE��,7�%024;�4p,abf���Ͱ��0cC �C6cՍ ��A��!�q��5�>@�]˼��F)���`Q�������@� � )#� Usual Interstitial Pneumonia Definition. Akira M, Inoue Y, Kitaichi M et-al. On imaging, usual interstitial pneumonia usually presents with a lung volume loss and a craniocaudal gradient of peripheral septal thickening, bronchiectasis, and honeycombing. A histologic pattern of nonspecific interstitial pneumonia is associated with a better prognosis than usual interstitial pneumonia in patients with cryptogenic fibrosing alveolitis. 28 Affected infants are generally full-term and develop symptoms and signs of lung disease within hours of birth, and radiographically have diffuse lung disease that resembles RDS in prematurely born infants. 8.

Lynch DA, Sverzellati N, Travis WD, et al. non-specific interstitial pneumonia (NSIP), desquamative interstitial pneumonia (DIP), connective tissue disorder interstitial lung disease, diagnostic HRCT criteria for UIP pattern - ATS/ERS/JRS/ALAT (2018), diagnostic HRCT criteria for UIP pattern - Fleischner society guideline (2018), fibrotic non-specific interstitial pneumonia, chronic hypersensitivity pneumonitis (HP), combined pulmonary fibrosis and emphysema (CPFE), acute unilateral airspace opacification (differential), acute bilateral airspace opacification (differential), acute airspace opacification with lymphadenopathy (differential), chronic unilateral airspace opacification (differential), chronic bilateral airspace opacification (differential), osteophyte induced adjacent pulmonary atelectasis and fibrosis, pediatric chest x-ray in the exam setting, normal chest x-ray appearance of the diaphragm, posterior tracheal stripe/tracheo-esophageal stripe, obliteration of the retrosternal airspace, leflunomide-induced acute interstitial pneumonia, cellular non-specific interstitial pneumonia, respiratory bronchiolitis–associated interstitial lung disease, diagnostic HRCT criteria for UIP pattern - ATS/ERS/JRS/ALAT (2011), diagnostic HRCT criteria for UIP pattern - Fleischner society guideline (2018)​, domestically acquired particulate lung disease, lepidic predominant adenocarcinoma (formerly non-mucinous BAC), micropapillary predominant adenocarcinoma, invasive mucinous adenocarcinoma (formerly mucinous BAC), lung cancer associated with cystic airspaces, primary sarcomatoid carcinoma of the lung, large cell neuroendocrine cell carcinoma of the lung, squamous cell carcinoma in situ (CIS) of lung, minimally invasive adenocarcinoma of the lung, diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH), calcifying fibrous pseudotumor of the lung, IASLC (International Association for the Study of Lung Cancer) 8th edition (current), IASLC (International Association for the Study of Lung Cancer) 7th edition (superseeded), 1996 AJCC-UICC Regional Lymph Node Classification for Lung Cancer Staging, connective tissue disorders (CTD associated UIP): falls under the borader spectrum of. IPF is the most important and common form of chronic intersti-tial lung disease (ILD). However more recently the term idiopathic pulmonary fibrosis has been applied solely to the clinical syndrome associated with the morphologic pattern of UIP, with the specific exclusion of entities such as non-specific interstitial pneumonia (NSIP) and desquamative interstitial pneumonia (DIP) 1. Usual interstitial pneumonia (UIP) is a form of lung disease characterized by progressive scarring of both lungs. Classification and natural history of the idiopathic interstitial pneumonias. Otaola M, Quadrelli S, Tabaj G et-al. European Respiratory Journal. NSIP is less common than UIP, but occurs more frequently than the remaining idiopathic interstitial pneumonias. 13. Assessment with serial CT. Usual interstitial pneumonia: relationship between disease activity and the progression of honeycombing at thin-section computed tomography. Set alert. Wuyts WA, Cavazza A, Rossi G et-al. These would include: In practice, the diagnosis is usually made in a multidisciplinary approach involving chest physicians, radiologists and pathologists with expertise in interstitial lung disease (ILD) 12.
