Jun 16, 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. Terminology.
Jun 19, 2024 · This helps radiologists to determine the certainty of usual interstitial pneumonia (UIP) diagnosis based on HRCT chest findings. The importance of this guideline is that (definite) UIP pattern on chest HRCT precludes the need for tissue diagnosis 1,2,5.
Extensive pulmonary fibrosis characterized by peripheral inter and intralobular septal thickening, traction bronchiectasis, and micro and macrocytic honeycombing. These demonstrate a relative craniocaudal gradient of distribution.
Nov 15, 2017 · A usual interstitial pneumonia (UIP) pattern on chest CT scans is highly suggestive of UIP pathologic findings; the most common cause of UIP is idiopathic pulmonary fibrosis (IPF) [1–5]. Under current guidelines, a UIP pattern on CT images is specific for IPF after a thorough clinical and serologic workup has excluded other causes of ...
Case Discussion. These findings are consistent with UIP pattern. UIP has distinctive HRCT findings. If the UIP pattern is of unknown cause (i.e. idiopathic), the disease is called idiopathic pulmonary fibrosis (IPF).
Idiopathic interstitial pneumonias comprise usual interstitial pneumonia (UIP), nonspecific interstitial pneumonia (NSIP), desquamative interstitial pneumonia (DIP), respiratory bronchiolitis–associated interstitial lung disease (RB-ILD), cryptogenic organizing pneumonia (COP), acute interstitial pneumonia (AIP), and lymphoid interstitial ...
Sep 3, 2016 · The interstitial pneumonias (IPs), or idiopathic interstitial pneumonias (IIPs), are a heterogeneous group of diffuse lung diseases characterized by varying degrees of lung inflammation and fibrosis. They are best thought of as reactions to lung injury, presenting with specific histologic patterns.
Jun 27, 2023 · 1. Distinguish UIP from IPF 2. Review histologic and imaging patterns of UIP; review updated 2022 ATS criteria diagnosis for IPF. 3. Explore the differential diagnosis for UIP and associated imaging findings including IPF, connective tissue disease, hypersensitivity pneumonitis, asbestosis, vasculitis, familial pulmonary fibrosis, and drug ...
Feb 1, 2014 · Purpose. To determine the accuracy of computed tomography (CT) in identifying the histopathologic usual interstitial pneumonia (UIP) pattern in rheumatoid arthritis–associated interstitial lung disease (RA-ILD). Materials and Methods.
Jul 21, 2019 · Idiopathic pulmonary fibrosis (IPF) has been defined as “a specific form of chronic fibrosing interstitial pneumonia limited to the lung and associated with the histologic and/or CT appearance of usual interstitial pneumonia (UIP).” IPF is the most common idiopathic interstitial lung disease.
