AB  - Organising pneumonia (OP) is currently recognised as a nonspecific lung injury response that is associated with a variety of imaging patterns obtained with high-resolution computed tomography (HRCT) of the chest and is characterised histopathologically by the presence of inflammatory cells and a connective tissue matrix within distal airspaces of the lungs. OP is associated with many conditions that include connective tissue disorders, various infections, drug reactions, hypersensitivity pneumonitis and aspiration. When OP cannot be linked to an associated condition and appears to be idiopathic, it is termed cryptogenic organising pneumonia.The diagnosis of cryptogenic organising pneumonia requires the clinician to be prudent in eliminating several clinical conditions including: environmental factors, medications, systematic disease, aspiration pneumonia and infection, including COVID-19 https://bit.ly/3vf9NVm
