A pulmonary consolidation is a region of normally compressible lung tissue that has filled with liquid instead of air. [1] The condition is marked by induration [2] (swelling or hardening of normally soft tissue) of a normally aerated lung. It is considered a radiologic sign.
Atelectasis of the right lower lobe seen on chest X-ray. Clinically significant atelectasis is generally visible on chest X-ray; findings can include lung opacification and/or loss of lung volume. Post-surgical atelectasis will be bibasal in pattern. Chest CT or bronchoscopy may be necessary if the cause of atelectasis is not clinically ...
Lobar pneumonia is a form of pneumonia characterized by inflammatory exudate within the intra-alveolar space resulting in consolidation that affects a large and continuous area of the lobe of a lung. [1] [2] It is one of three anatomic classifications of pneumonia (the other being bronchopneumonia and atypical pneumonia).
People who aspirate while standing can have bilateral lower lung lobe infiltrates. The right upper lobe is a common area of consolidation, where liquids accumulate in a particular region of the lung, in alcoholics who aspirate in the supine position. [15]
On high resolution computed tomography, airspace consolidation with air bronchograms is present in more than 90% of patients, often with a lower zone predominance. A subpleural or peribronchiolar distribution is noted in up to 50% of patients. Ground glass appearance or hazy opacities associated with the consolidation are detected in most patients.
Lower respiratory tract infection (LRTI) is a term often used as a synonym for pneumonia but can also be applied to other types of infection including lung abscess and acute bronchitis. Symptoms include shortness of breath , weakness, fever , coughing and fatigue. [ 3 ]
Infiltrate or consolidation - Opacification of airspaces within the lung parenchyma. Consolidation or infiltrate can be dense or patchy and might have irregular, ill-defined, or hazy borders. Dense homogenous opacity in right, middle and lower lobe of primary pulmonary TB.
During initial stages, this is most often found in the lower lobes, although involvement of the upper lobes and right middle lobe has also been reported early in the disease course. [ 16 ] [ 18 ] This is in contrast to the two similar coronaviruses, SARS and MERS , which more commonly involve only one lung on initial imaging.
