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.

This is in contrast to systemic sclerosis, most cases of which have an NSIP pattern [ 24, 28, 29 ]. UIP is much less common in systemic sclerosis than in rheumatoid arthritis. Introduction. Diffuse pulmonary ossification (DPO) in patients without background lung disease is a rare condition (1.63 of 1000 cases at autopsy) ().The cause of the deposition of numerous small ossified nodules throughout the lung parenchyma is unknown (2,3). Non-specific interstitial pneumonia typically tends to present in middle-aged adults, 40-50 years of age 1. It may be common in Caucasian-European populations 9. Overall prevalence is higher in women due to high association with collagen vascular diseases, but the prevalence of idiopathic NSIP is similar in both genders.

Clinical Considerations Patients with UIP or fibrotic NSIP who have a high fibrotic score (the extent of reticulation plus HC) at TSCT and a low DLco level appear to have a high death risk [ 5 ].

NSIP is a rare condition with take part of approximately 25% of the interstitial lung diseases, which is far less than UIP pattern (60% of ILD). Clinical features of fibrotic NSIP (Commoner type of NSIP) is almost similar to the idiopathic pulmonary fibrosis (IPF / UIP).

Fibrosis usually lower lung zone. Patchy ground glass.

Features: Diffuse fibrosis: NSIP is temporally and spatially homogeneous, while UIP is typically heterogeneous, patchy, and irregular in size. 36 The extent of honeycombing and traction bronchiectasis is greater in UIP than the extent of ground glass opacity or micronodules, which are more commonly associated with an NSIP pattern. 5 36 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.

Non-specific interstitial pneumonia (NSIP) is the second most common morphological and pathological pattern of interstitial lung diseases. NSIP has two main 

This outcome is quite different from that seen in UIP, which has a poor prognosis. IIPs include seven entities: idiopathic pulmonary fibrosis, which is characterized by the morphologic pattern of usual interstitial pneumonia (UIP); nonspecific interstitial pneumonia (NSIP); cryptogenic organizing pneumonia (COP); respiratory bronchiolitis–associated interstitial lung disease (RB-ILD); desquamative interstitial pneumonia (DIP); lymphoid interstitial pneumonia (LIP); and acute interstitial pneumonia (AIP). Se hela listan på There are two primary histopathologic patterns of ILD that are observed in patients with RA-associated ILD (hereafter, RA-ILD), the nonspecific interstitial pneumonia (NSIP) pattern and the usual interstitial pneumonia (UIP) pattern (3–5). Other less common patterns include organizing pneumonia and obliterative bronchiolitis (2,6). Nonspecific interstitial pneumonia (NSIP) is a chronic interstitial lung disease characterized by homogeneous expansion of the alveolar walls by inflammation or fibrosis or both. NSIP is the second most common chronic interstitial pneumonia, after usual interstitial pneumonia (UIP), accounting for 14% to 35% of cases.

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.

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 2017-11-29 Obtaining a confident radiologic diagnosis is often difficult as the features of interstitial lung diseases often have significant overlap. Distinguishing between UIP, NSIP, and chronic fibrotic hypersensitivity pneumonitis is often difficult in clinical practice as the HRCT findings only allow a confident diagnosis 50% of the time. 9 Key NSIP may also demonstrate bronchovascular distribution of lung lesions and subpleural distribution as well (Fig. 20.4).

Most patients with CTD have extra-pulmonary manifestations but in some cases, lung abnormalities are seen in isolation or as the first manifestation of disease. This chapter provides an overview of the approach to diagnosis of lung … Surgical lung biopsy is required for a diagnosis of NSIP. Histologically, most patients have some degree of fibrosis. Histologically, most patients have some degree of fibrosis. The main feature of NSIP is temporally homogenous inflammation and fibrosis, as opposed … Organizing pneumonia is caused by inflammation 10 and may be idiopathic in nature, termed cryptogenic organizing pneumonia, or may occur secondary to infection, collagen vascular disease, or drug toxicity. 35 Organizing pneumonia is characterized by the presence of consolidation and may also show features of fibrosis reminiscent of NSIP.
