20 hours ago · Several key features can help to distinguish NSIP from UIP. While helpful, the differences between UIP and NSIP are often not as obvious as this figure suggests, and the difficulty lies in distinguishing the cases that lie toward the middle.

Oct 14, 2024 · Usual interstitial pneumonia (UIP) is not a disease, it is a histopathologic and radiologic pattern of interstitial lung disease. This can be caused by idiopathic pulmonary fibrosis, fibrotic hypersensitivity pneumonitis or non-specific interstitial pneumonia. The diagnosis is typically decided by a multidisciplinary team.

Jun 19, 2024 · However, unfortunately up to 20% of inconsistent with UIP group (or actually atypical UIP) can be UIP on biopsy or progress clinically to a diagnosis of idiopathic pulmonary fibrosis (IPF). UIP pattern. Classic HRCT pattern including: honeycombing: it is the distinguishing feature of UIP and must be present +/- traction bronchiectasis

Sep 12, 2018 · PPFE, the newest pathologic subcategory, is rare and highlighted by pleural thickening predominantly in the upper lobes. It is often associated with parenchymal or interstitial findings on CT, most commonly UIP and NSIP.

Dec 20, 2007 · In this review we present the key findings in the most common interstitial lung diseases. There are numerous interstitial lung diseases, but in clinical practice only about ten diseases account for approximately 90% of cases.

Usual interstitial pneumonia (UIP) is a form of lung disease characterized by progressive scarring of both lungs. [1] The scarring (pulmonary fibrosis) involves the pulmonary interstitium (the supporting framework of the lung). UIP is thus classified as a form of interstitial lung disease.

In this review, the evolutionary concepts of UIP, NSIP, and ILA are summarized using tables, figures, and CT-pathologic correlation. Finally, the proposal of CT-based UIP scoring was proposed to facilitate a better understanding of the spectrum from ILA to UIP with attention to traction bronchiectasis.

Background: Both a probable usual interstitial pneumonia (UIP) pattern (p-UIP) and a definite UIP pattern (d-UIP) on high-resolution computed tomography (HRCT) are sufficient to establish a diagnosis of idiopathic pulmonary fibrosis (IPF) without ...

Feb 13, 2018 · Dr. Mukhopadhyay highlights the differences in Usual Interstitial Pneumonia (UIP) and Nonspecific Interstitial Pneumonia (NSIP), and explains what a pathologist should look for when determining the patient’s diagnosis.
