2017-09-20 · Nonspecific interstitial pneumonia (NSIP), either idiopathic or secondary to other disease, is also best considered a pattern of lung injury, but differs from UIPs as the interstitial changes are relatively homogeneous.

In this study of patients with histologically well defined UIP and NSIP we found that: (1) patients with an HRCT pattern of UIP are likely to have a histopathological pattern of UIP, but patients with an HRCT pattern other than UIP may have either a histological pattern of UIP or NSIP on the surgical lung biopsy specimen; (2) HRCT features add prognostic information to the histological

It is important to differentiate NSIP from other diffuse lung diseases, especially usual interstitial pneumo-nia and hypersensitivity pneumonitis, owing to differences in prog-nosis and treatment. At high-resolution computed tomography, the most common findings suggestive of NSIP are lower lobe peripherally Lung biopsies performed on patients with NSIP reveal two different disease patterns – cellular and fibrosing – which are associated with different prognoses. The cellular pattern displays chronic inflammation with minimal fibrosis. The fibrosing pattern displays interstitial fibrosis with various inflammation levels. CONCLUSION: In patients with a clinical presentation of idiopathic pulmonary fibrosis, the accuracy of thin-section CT in identifying NSIP is considerably higher than previously reported.

High-power photomicro-graph (original magnification, ×20; hematoxylin-eosin [H-E] stain) of a section of lung tissue shows the ho-mogeneous septal thickening characteristic of NSIP. Alveolar septa are expanded by both chronic inflam-mation and a small amount of collagen. Pathology. The pathogenesis of pulmonary involvement relates to separate mechanisms: direct involvement. scleroderma-related interstitial lung disease (SSc-ILD) usual interstitial pneumonia (UIP) pattern: histologically indistinguishable from rheumatoid lung and idiopathic pulmonary fibrosis (IPF) an NSIP type can also occur fine reticulation. reticular opacities and irregular linear opacities (sometimes – minor subpleural reticulation).

Pulmonary pathologist Sanjay Mukhopadhyay, MD, highlights the differences between Usual Interstitial Pneumonia (UIP) and Nonspecific Interstitial Pneumonia (

When idiopathic, NSIP is considered one of the idiopathic interstitial pneumonias (IIPs), which also include usual interstitial pneumonia (UIP)/idiopathic pulmonary fibrosis (IPF), desquamative interstitial pneumonia (DIP), respiratory bronchiolitis-associated interstitial lung disease (RB-ILD), acute interstitial pneumonia (AIP), and

Lære mer. Den nuvarande teorin föreslår att UIP orsakas av små foci av akut lungskada andra typer av fibroserande interstitiella lungsjukdomar, särskilt UIP och NSIP. An interstitial lung disease with a histologic NSIP pattern, due to a variety of etiologies The NSIP pattern is the second most common pattern, and always part of the differential diagnosis of the usual interstitial pneumonia (UIP) pattern, but NSIP has a better prognosis than UIP NSIP is a diagnosis of exclusion; The following features should not be seen Granulomas or giant cells; Bronchiolocentric distribution; Acute lung injury pattern / hyaline membranes; More than rare eosinophils; Evidence of infection idiopathic NSIP, NSIP due to an underlying cause LM DDx organizing pneumonia , collagen vascular disease , drug reaction, hypersensitivity pneumonitis , lymphocytic interstitial pneumonia NSIP is a diagnosis of exclusion, since numerous other inflammatory and fibrotic processes involving the lung may have NSIP-like areas, including hypersensitivity pneumonia, UIP, DAD, LIP, DIP, Nonspecific interstitial pneumonia (NSIP) is a rare disorder that affects the tissue that surrounds and separates the tiny air sacs of the lungs. These air sacs, called the alveoli, are where the exchange of oxygen and carbon dioxide takes place between the lungs and the bloodstream. With interstitial pneumonia the mesh-like walls of the alveoli become inflamed.

At CT, NSIP is characterized by more ground-glass attenuation and a finer reticular pattern than is UIP. NSIP is the prevalent lung pattern in systemic sclerosis and polymyosisits/dermatomyositis (more than 90%), but also may occur in RA, SLE, Sj?gren's and MCTD. In the images on your left you can appreciate again the spectrum of findings seen in NSIP. Non-specific interstitial pneumonia (NSIP) is an interstitial lung disease that may be idiopathic or secondary to connective tissue disease, toxins or numerous other causes. Idiopathic NSIP is a rare diagnosis and requires exclusion of these other possible causes. Pathology Poster : Non-Specific Interstitial Pneumonia (NSIP) Nonspecific interstitial pneumonia (NSIP) has been proposed as a histologic subtype of idiopathic interstitial pneumonia with lung biopsy findings that are inconsistent with those of other idiopathic interstitial pneumonias.

Both are temporally uniform and have interstitial inflammation Absence of hyaline membranes and other findings of acute lung injury, granulomas, organisms or viral inclusions, dominant airways disease, eosinophils, dense interstitial fibrosis, diffuse severe alveolar septal inflammation, and organizing pneumonia involving <20% of the biopsy specimen are considered important negative findings helping to distinguish NSIP from other interstitial lung diseases. 2020-01-02 2017-09-20 2011-06-07 All other types of interstitial lung disease must be ruled out. Features of other types of interstitial lung disease should not be present Diffuse filling of alveoli by macrophages typical of DIP, see note below; Focal fibroblastic foci or honeycomb pattern typical of UIP; Diffuse involvement of NSIP; Hyaline membranes or organization of AIP Heterogeneous pattern of alternating honeycombing and normal lung with intermediate zones of inflammation and active fibrosis; Spatially heterogeneous fibrosis.
