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.

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.

Oct 3, 2022 · Interstitial pneumonia is a group of diseases where inflammation and fibrosis damage small air-filled spaces inside the lungs called alveoli. Over time, the damage leads to scarring which prevents the lungs from working properly.

Current guidelines describe three UIP patterns based on HRCT findings: a typical UIP pattern (which eliminates the need for surgical lung biopsy); a pattern designated “possible UIP”; and a pattern designated “inconsistent with UIP”, surgical lung biopsy being required in patients presenting with either of the last two patterns. 1, 2, 4 ...

Jun 19, 2024 · HRCT features of pulmonary fibrosis that do not meet the "UIP" or "probable UIP" patterns above and does not explicitly suggest an "alternative diagnosis".

Sep 12, 2018 · The interstitial pneumonias (IPs) are a heterogeneous group of diffuse parenchymal lung diseases characterized by specific clinical, radiologic and pathologic features. While pathologically defined, significant overlap in terms of presentation as well as association with secondary diseases is known and may confound initial work-up and diagnosis.

Feb 28, 2022 · Usual interstitial pneumonia (UIP) is best known as the pathologic correlate of the clinically defined entity idiopathic pulmonary fibrosis (IPF) 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12.

Nov 9, 2020 · Usual interstitial pneumonia (UIP) is a distinct histological lesion observed in idiopathic pulmonary fibrosis (IPF) but can be found in other etiologies. The diagnosis of UIP can be established by surgical lung biopsy or by high-resolution thin-section computed tomographic (CT) scans (provided the …

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...

May 1, 2007 · IIPs include seven entities: idiopathic pulmonary fibrosis, which is characterized by the morphologic pattern of usual interstitial pneumonia (UIP); nonspecific interstitial pneumonia (NSIP); cryptogenic organizing pneumonia (COP); respiratory bronchiolitis–associated interstitial lung disease (RB-ILD); desquamative interstitial pneumonia ...
