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. Primarily idiopathic but the morphological pattern can be seen in association with a number of conditions: 1. connective tissue disorders 1.1. systemic lupus eryth…

The affected portions of lung in NSIP may worsen uniformly over time, giving rise to the florid honeycombing pattern of end-stage disease. 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.

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 may also demonstrate bronchovascular distribution of lung lesions and subpleural distribution as well (Fig. 20.4). 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 ]. Purpose: The purpose of this article was to determine whether a novel finding on coronal computed tomography (CT) can help differentiate usual interstitial pneumonia (UIP) from nonspecific interstitial pneumonia (NSIP) in order to obviate lung biopsy.

In cases of ﬁbrotic NSIP, serial CT reveals an The affected portions of lung in NSIP may worsen uniformly over time, giving rise to the florid honeycombing pattern of end-stage disease. 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 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).

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.

In 5 to 10% of patients the chest radiograph is normal. 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.

A patchy and geographic distribution of GGO, with significant involvement of the central lung, is not typical of an interstitial pneumonia (i.e., NSIP, DIP, LIP, and OP), but is occasionally seen with NSIP in patients with connective tissue disease or LIP. HRCT Interpretation Algorithm for Suspected Fibrotic Interstitial Lung Disease. If airway-centric disease has been ruled out and interstitial lung disease is suspected, making the distinction between fibrosing and non-fibrosing interstitial lung disease is imperative to narrow the differential diagnosis. 10 Once it has been established that the underlying disorder is fibrotic in nature, the NSIP is the diagnosis as Interstitial Lung Disease (ILD) with clinical significance, whereas only a part of subjects with ILA have clinically significant ILD. Eventually, both ILA and NSIP must be understood in the context of chronic fibrosing ILD and progressive ILD, which remains to be further investigated. Welcome to the Radiology Assistant Educational site of the Radiological Society of the Netherlands by Robin Smithuis MD Lung cysts are defined as radiolucent areas with a wall thickness of less than 4mm.

However, the subpleura is relatively normal in this case, and this patient’s disease has a central, bronchovascular distribution, which is the hallmark feature of NSIP … Quiz: Differentiating Between Chronic HP, NSIP, A Radiology Perspective TLC, total lung capacity.

This outcome is quite different from that seen in UIP, which has a poor prognosis. 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) Lymphocytic interstitial pneumonitis is a benign lymphoproliferative disorder characterized by lymphocyte predominant infiltration of the lungs. It is classified as a subtype of interstitial lung disease.

Clinical; Insidious onset of dyspnea, cough, fatigue; Mean age 40-50, may be seen in children; Pulmonary function tests: restrictive with decreased diffusing capacity The HRCT appearance of pulmonary sarcoidosis varies greatly and is known to mimic many other diffuse infiltrative lung diseases. Approximately 60 to 70% of patients with sarcoidosis have characteristic radiologic findings. In 25 to 30% of cases the radiologic findings are atypical.

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 patchy peripheral or peribronchovascular consolidation.

Note the "patchwork" (quilt-like) pattern of the fibrosis. Of the idiopathic interstitial pneumonias, idiopathic pulmonary fibrosis (IPF) and nonspecific interstitial descriptions for NSIP, the accuracy of radiologists in.

In many patients the high resolution CT scan of the lungs provides enough information to confirm IPF or NSIP. In some patients there is no way to distinguish IPF from NSIP without a lung biopsy. At present, the best type of lung biopsy is a VATS (video-assisted thoracoscopic surgery).

In the images on your left you can appreciate again the spectrum of findings seen in NSIP.

The CT features of lung disease in patients with SSc closely resemble those in patients with idiopathic NSIP. Fibrotic NSIP (fig 1 B): The fibrotic type has a preserved architecture.
