Oct 14, 2024 · In general, UIP can be divided into two groups, those with <5% honeycombing and those with >5% honeycombing. It mainly reflects the stage and severity of the disease.

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.

Jun 19, 2024 · UIP pattern. Classic HRCT pattern including: honeycombing: it is the distinguishing feature of UIP and must be present +/- traction bronchiectasis; reticular abnormalities; distribution: subpleural with a basal predominance; absence of features suggestive of an alternative diagnosis Probable UIP pattern. HRCT studies with absent honeycombing ...

Jan 7, 2021 · In this article we will discuss lung diseases with a reticular pattern and provide a guidance for radiologists to evaluate the most common diseases and their patterns. A stepwise approach is presented to identify the key features in fibrotic lung disease and to make it easier to reach a differential diagnosis.

Sep 12, 2018 · A first approach is to separate the eight pathologically defined patterns into six major (UIP, NSIP, COP, DIP, RB-ILD, AIP) and two rare or less commonly encountered entities (LIP and PPFE). Of the six major patterns, a review of their courses and presentations as well as associated clinical findings further leads to three subcategorizations:

Current guidelines describe three UIP patterns based on HRCT findings: a typical UIP pattern; a pattern designated “possible UIP”; and a pattern designated “inconsistent with UIP”, each pattern having important diagnostic implications.

Oct 3, 2022 · Usual interstitial pneumonia (UIP) is a disease where inflammation damages the airspaces in the lung. Idiopathic pulmonary fibrosis is a type of UIP.

Jun 19, 2024 · The 2018 revised diagnostic HRCT criteria for usual interstitial pneumonia (UIP) pattern published by the American Thoracic Society, the European Respiratory Society, the Japanese Respiratory Society, and the Latin American Thoracic Association has converged to a similar categorisation of the HRCT findings into four groups.

Over time, as the understanding of the clinical behavior and histologic features of the IIPs has evolved, the categories of IIP have changed: usual interstitial pneumonia (UIP) and desquamative interstitial pneumonia (DIP) have persisted as important histologic groups, nonspecific interstitial pneumonia (NSIP) has been added, and bronchiolitis o...

Jan 2, 2020 · Usual interstitial pneumonia (UIP) refers to a morphologic entity defined by a combination of (1) patchy interstitial fibrosis with alternating areas of normal lung, (2) temporal...
