Cystic lung diseases as listed in the table on the left. Cavities are defined as radiolucent areas with a wall thickness of more than 4mm and are seen in infection (TB, Staph, fungal, hydatid), septic emboli, squamous cell carcinoma and Wegener's disease. Fibrotic NSIP (fig 1 B): The fibrotic type has a preserved architecture. Bronchiolar metaplasia, smooth muscle metaplasia, and honeycombing may be present.

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. NSIP may be idiopathic or associated with collagen vascular diseases or exposure to drugs or chemicals. NSIP has a relative good prognosis and the majority of patients respond to treatment with corticosteroids. 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.

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.

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.

9 Key NSIP may also demonstrate bronchovascular distribution of lung lesions and subpleural distribution as well (Fig. 20.4).

If no underlying cause is present it is known as idiopathic NSIP. Clinical features (typical) of the idiopathic form: Middle-aged, never-smoker women. Dyspnea. Cough. Ground glass on HRCT. Very good prognosis. Gross/Radiology. No honeycombing. Fibrosis usually lower lung zone. Patchy ground glass. Microscopic. Features: Diffuse fibrosis:

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 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.

At high-resolution computed tomography, the most common findings suggestive of NSIP are lower lobe peripherally 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.

10 Once it has been established that the underlying disorder is fibrotic in nature, the A peripheral distribution of findings with sparing of the immediate subpleural lung is highly suggestive of NSIP . 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. Welcome to the Radiology Assistant Educational site of the Radiological Society of the Netherlands by Robin Smithuis MD 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. Lung cysts are defined as radiolucent areas with a wall thickness of less than 4mm. Cystic lung diseases as listed in the table on the left.

However, whether or not NSIP outcome is influenced by the underlying 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 A peripheral distribution of findings with sparing of the immediate subpleural lung is highly suggestive of NSIP .
