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.
To confirm the diagnosis, a doctor may perform a lung biopsy using a bronchoscope. Many times, a larger specimen is needed and must be removed surgically. Plain chest radiography shows normal lung volumes, with characteristic patchy unilateral or bilateral consolidation. Small nodular opacities occur in up to 50% of patients and large nodules ...
Radiation pneumonitis occurs in approximately 30% of advanced lung cancer patients treated with radiation therapy. [16] Aspiration pneumonitis is caused by a chemical inhalation of harmful gastric contents which include causes such as: Aspiration due to a drug overdose [17] A lung injury after the inhalation of habitual gastric contents. [17]
Pulmonary contusion can cause parts of the lung to consolidate, alveoli to collapse, and atelectasis (partial or total lung collapse) to occur. [35] Consolidation occurs when the parts of the lung that are normally filled with air fill with material from the pathological condition, such as blood. [ 36 ]
However, some patients have worsening symptoms and imaging findings, with further increase in septal thickening, GGOs, and consolidation. These patients may develop lung "white-out" with progression to acute respiratory distress syndrome (ARDS) requiring treatment escalation. [17] [21]
Pneumonia is an inflammatory condition of the lung primarily affecting the small air sacs known as alveoli. [3] [14] Symptoms typically include some combination of productive or dry cough, chest pain, fever, and difficulty breathing. [15]

Anatomically, the lung structure, alveolar organization, and alveolar capillaries contribute to the physiological mechanism of ventilation and perfusion. [1] Ventilation–perfusion coupling maintains a constant ventilation/perfusion ratio near 0.8 on average, while the regional variation exists within the lungs due to gravity.
