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 Knowledge of the lung anatomy is essential for understanding HRCT. The interpretation of interstitial lung diseases is based on the type of involvement of the secondary lobule. The secondary lobule is the basic anatomic unit of pulmonary structure and function. It is the smallest lung unit that is surrounded by connective tissue septa. Se hela listan på radiopaedia.org gree of inflammation and fibrosis.
Non-specific interstitial pneumonia is an interstitial pathology of the lung associated with varying degree of interstitial inflammation and fibrosis. It is called as non-specific interstitial pneumonia, due to it’s lack of histopathological features compared to other types of interstitial pneumonia. 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.
Cellular and fibrotic NSIP are the two main histologic subtypes and differ from one another in the degree of inflammation and fibrosis. Non-specific interstitial pneumonia is an interstitial pathology of the lung associated with varying degree of interstitial inflammation and fibrosis. It is called as non-specific interstitial pneumonia, due to it’s lack of histopathological features compared to other types of interstitial pneumonia.

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). It is thus not currently excluded that NSIP is a somewhat different response by the lung to one and the same triggering mechanism.

NSIP nonspecific interstitial p.
Idiopathic, nonspecific interstitial pneumonia (NSIP) is most often associated with various clinical disorders, including connective tissue diseases (CTDs) and chronic hypersensitivity pneumonitis (cHP).
This is also supported by the differentiation already discussed between the cellular and fibrotic NSIP, in which fibrotic NISP may indeed have a clinical course that resembles IPF, while cellular NSIP often responds to steroids and prognostically is much more 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.
35 Organizing pneumonia is characterized by the presence of consolidation and may also show features of fibrosis reminiscent of NSIP. 10. 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.
