Nonspecific Interstitial Pneumonia. NSIP is a chronic, fibrotic interstitial pneumonia, which carries a better prognosis than UIP. 34 35 Of the idiopathic interstitial pneumonias, NSIP is the most difficult to distinguish from UIP. 3 NSIP often occurs secondary to a known condition such as connective tissue disease, hypersensitivity pneumonitis, or drug toxicity. 35 The predominant features

NSIP Radiology NSIP – Non Specific Interstitial Pneumonia Non-specific interstitial pneumonia is an interstitial pathology of the lung associated with varying degree of interstitial inflammation and fibrosis.

The straight-edge sign may be related to the peribronchovascular axial distribution of many NSIP cases; as disease extent increases, fibrosis may then extend out to the lateral margins of the lung, producing the straight-edge sign. NSIP is characterized by predominantly basal ground-glass opacity and/or reticular pattern, often with traction bronchiectasis. DIP and RB-ILD are smoking-related lung diseases characterized by ground-glass opacity and centrilobular nodules. COP is characterized by … Nonspecific Interstitial Pneumonia Jud W. Gurney, MD, FACR Tan-Lucien H. Mohammed, MD, FCCP Key Facts Terminology 1 of the idiopathic interstitial pneumonias, less common than idiopathic pulmonary fibrosis (IPF), but with better prognosis than IPF Imaging Findings Ground-glass opacities > reticular opacities Traction bronchiectasis out of proportion to reticular opacities May have fine Katzenstein first described NSIP in 1994. The term is used for cases of interstitial pneumonia in which diagnostic features of UIP, DIP, AIP, or COP are not present.

Cough. Ground glass on HRCT. Very good prognosis.

NSIP can also be a manifestation of familial ILD (45–47). Also, the NSIP pattern may represent the sole or predominant morphology on surgical lung biopsy in a number of cases in which the CRP diagnosis is subacute or chronic hypersensitivity pneumonitis (48, 49).

In the images on your left you can appreciate again the spectrum of findings seen in NSIP. 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; scleroderma-related pulmonary arterial hypertension (SSc-PAH) NSIP may be idiopathic or associated with collagen vascular diseases or exposure to drugs or chemicals.

At present, the best type of lung biopsy is a VATS (video-assisted thoracoscopic surgery). Comment in Radiology. 2001 Dec;221(3):583-4. PURPOSE: To compare the morphologic abnormalities on thin-section computed tomographic (CT) images in a group of patients with histopathologically confirmed nonspecific interstitial pneumonia (NSIP) or usual interstitial pneumonia (UIP) and a clinical presentation of idiopathic pulmonary fibrosis. typical findings in nsip Spatially homogeneous pattern of fibrosis seen in non specific interstitial pneumonia (NSIP) (trichrome stain X40) Courtesy Medscape eMedicine Interstitial lung disease in patients with SSc is less extensive, less coarse, and characterized by a greater proportion of ground-glass opacification than that in patients with IPF. The CT features of lung disease in patients with SSc closely resemble those in patients with idiopathic NSIP.

Interstitial lung disease in patients with SSc is less extensive, less coarse, and characterized by a greater proportion of ground-glass opacification than that in patients with IPF. The CT features of lung disease in patients with SSc closely resemble those in patients with idiopathic NSIP. This review article aims to address mysteries existing between Interstitial Lung Abnormality (ILA) and Nonspecific Interstitial Pneumonia (NSIP). The concept and definition of ILA are based upon CT scans from multiple large-scale cohort studies, whereas the concept and definition of NSIP originally derived from pathology with evolution to multi-disciplinary diagnosis. 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 Thus, using the classification scheme described by Katzenstein and Myers , findings consistent with NSIP were found in 18 of 22 (81.8%) of the surgical lung biopsies. Pulmonary Function Impairment of pulmonary function was predominantly restrictive, with total lung capacity 67.6 ± 14.0% (mean ± SD) predicted, and was below 80% of the predicted value in 27 of 33 patients tested. 2021-04-09 · At our division, we are often dealing with patients with a “typical” phenotype of idiopathic NSIP, as it has now been described , such as a middle-aged never-smoker woman, presenting with dyspnea and cough of 6 to 7 months duration, with a restrictive ventilatory pattern, with bilateral, symmetric, predominantly lower lung reticular opacities at HRCT and diffuse ground glass, without any Idiopathic, nonspecific interstitial pneumonia (NSIP) is most often associated with various clinical disorders, including connective tissue diseases (CTDs) and chronic hypersensitivity pneumonitis (cHP).

In contrast, traction bronchiolectasis, of which honeycombing consists in UIP, is seldom connected with a bronchus, as dilated bronchioles are elongated and distorted (15).

BAL shows either a neutrophilic or lymphocytic alveolitis (the incidence for each being approximately 50%). Radiologically, NSIP patients noticeably have above all a ground glass appearance as the main finding on the HRCT; these are generally predominantly symmetrical and in a subpleural location.
