Interstitial lung disease (ILD), or diffuse parenchymal lung disease (DPLD), is a group of respiratory diseases affecting the interstitium (the tissue and space around the alveoli (air sacs) of the lungs. 11. It is sometimes used incorrectly as a synonym for idiopathic pulmonary fibrosis. 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. 1996;110 (2): 378-82. Pathology Outlines. Pneumothorax is a common complication and can occur at presentation or at other times during the course of the disease. However, in certain conditions such as leflunomide-induced acute interstitial pneumonia, patients have pre-existing lung disease. Kim EA, Lee KS, Johkoh T et-al.

Over time, as the understanding of the clinical behavior and histologic features of the IIPs has evolved, the categories of IIP have changed: usual interstitial pneumonia (UIP) and desquamative interstitial pneumonia (DIP) have persisted as important histologic groups, nonspecific interstitial pneumonia (NSIP) has been added, and bronchiolitis obliterans with classical interstitial pneumonia (BIP) and giant cell … Meta-analysis of the radiological and clinical features of Usual Interstitial Pneumonia (UIP) and Nonspecific Interstitial Pneumonia (NSIP). Chung JH, Lynch DA. Usually, due to the more extensive involvement of the lower lobes, the major fissure is shifted inferiorly which is best seen on the lateral chest radiograph. h�mo�6ǿ Wells AU. Similar to the pathology specimen, cross-sectional imaging also reveals heterogeneity, with patchy areas of fibrosis alternating with areas of normal lung 5. Usual interstitial pneumonia and non-specific interstitial pneumonia: serial thin-section CT findings correlated with pulmonary function. IPF is the most important and common form of chronic intersti-tial lung disease (ILD). Usual interstitial pneumonia (UIP) defines idiopathic pulmonary fibrosis and is the most common of the idiopathic interstitial pneumonias. Respir. The distribution of UIP characteristically is with an apicobasal gradient with basal and peripheral (subpleural) predominance, although it is often patchy. 7. 10. asbestos-related interstitial lung disease: reticular opacity-to-ground glass opacity ratio: one or greater, HP usually involves the mid and upper zones of the lung, and also the presence of centrilobular nodules and areas of air trapping are very useful hints to differentiate it from UIP, UIP cases are also thought to have honeycombing and peripheral or lower lung zone predominance of disease, and less likely to have.

Acute interstitial pneumonia (AIP) is an idiopathic interstitial lung disease that is clinically characterized by sudden onset of dyspnea and rapid development of respiratory failure. As described in the 2002 statement, the pathology of IPF is that of usual interstitial pneumonia (UIP). Human lung disease due to an inability to produce SP-B was the first recognized genetic cause of surfactant dysfunction. [1, 2] AIP is histologically characterized by diffuse alveolar damage with subsequent fibrosis. 5
2014;14 Suppl 1: S2. The term usual interstitial pneumonitis (UIP) has also often been used, but again, the -itis part of that name may overemphasize inflammation. Gruden J. American Journal of Roentgenology. 16. Differential diagnosis of usual interstitial pneumonia: when is it truly idiopathic?. The term “bronchiolitis obliterans organizing pneumonia (BOOP)” is a relatively recent term for a clinicopathologic entity that has been recognized for some time.1 The name derives from a series of cases collected in the 1970s and 1980s by Charles Carrington.

Pathology of Usual Interstitial Pneumonia (UIP) Dr Sampurna Roy MD Usual interstitial pneumonia is the most common form of idiopathic interstitial fibrosis (70% of all cases), and unfortunately carries a poor prognosis.

In those with more active inflammation involving the pulmonary interstitium, there is a faster progression of honeycombing in long-term follow-up 10. On imaging, usual interstitial pneumonia usually presents with a lung volume loss and a craniocaudal gradient of peripheral septal thickening, bronchiectasis, and honeycombing. doi : 10.1038/modpathol.2011.154 .

What every radiologist should know about idiopathic interstitial pneumonias. The positive predictive value of CT in the diagnosis of UIP is high and ranges from 70-100% 1. On a typical biopsy, there are areas of normal lung alternating with interstitial fibrosis and honeycombing. Acute interstitial pneumonia (AIP) is a rapidly progressive condition of unknown cause that occurs in a previously healthy individual and produces the histologic findings of diffuse alveolar damage ().Because of its acute presentation and histologic features similar to those of acute respiratory distress syndrome (ARDS), AIP has been considered an idiopathic form of ARDS (1, 2). %PDF-1.6

Honeycombing, particularly if it involves more than 5% of the lung volume, is an almost 100% specific finding. In recent times some authors have suggested certain signs within a UIP pattern more suggestive of it being due to connective tissue disorder interstitial lung disease over IPF 22. Survival appears to be favorable. Idiopathic pulmonary fibrosis (IPF), the most common and lethal of the idiopathic interstitial pneumonias, is defined by a radiological and/or pathological pattern of usual interstitial pneumonia (UIP). Geographic variability means there are some areas of advanced scarring while other areas are completely normal. Classification and natural history of the idiopathic interstitial pneumonias. 3. Types of interstitial pneumonias One prominent example is the specific pattern of a usual interstitial pneumonia (UIP), which is further classified in a definite, probable or possible UIP pattern according to the current guidelines. 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. Usual Interstitial Pneumonia (UIP) is the pattern of fibrosis classically described as having geographic and temporal variability. It is rarely the sole major lung biopsy finding in patients presenting with interstitial lung disease (PBM-ILD). Idiopathic interstitial pneumonia is a term that encompasses the following entities: usual interstitial pneumonia (UIP), desquamative interstitial pneumonia (DIP), acute interstitial pneumonia (AIP), and nonspecific interstitial pneumonia (NSIP) 1.Several recent studies have demonstrated variable treatment responses and survival based on this classification 2–8.
