![]() Depending on the type of alveolar lung disease, the listener may hear "crackles" that indicate an excess of fluid in the lungs or an absence of lung sounds in certain regions which may indicate poor ventilation due to consolidation of pus or fibrosis. Patients with alveolar lung disease may have difficulty breathing and/or a cough which may be productive of sputum or blood.Ī physician will listen to the patient's lungs to help determine if there is likely a lower lung disease. Causes of acute alveolar lung disease include pulmonary edema (cardiogenic or neurogenic), pneumonia (bacterial or viral), systemic lupus erythematosus, bleeding in the lungs (e.g., Goodpasture syndrome), idiopathic pulmonary hemosiderosis, and granulomatosis with polyangiitis.Ĭhronic alveolar lung disease can be caused by pulmonary alveolar proteinosis, alveolar cell carcinoma, mineral oil pneumonia, sarcoidosis (alveolar form), lymphoma, tuberculosis, metastases, or desquamative interstitial pneumonia.ĭiagnosis Initial evaluation and Testing There are a number of different causes of insult to the alveoli including build up of fluid, hemorrhage, infection, malignancy and build up of protein and mineral deposits.Ĭonditions classified under alveolar lung disease include pulmonary edema (cardiogenic or non-cardiogenic), pneumonia (bacterial or viral), bronchoalveolar carcinoma, pulmonary hemorrhage, alveolar proteinosis and amyloidosis, and alveolar microlithiasis.Īlveolar lung disease may be divided into acute or chronic. Alveolar lung diseases are classified as processes that affect these units that ultimately lead to issues with ventilation. Causes Īlveoli are the functional units of the lungs. Alveolar lung diseases, are a group of diseases that mainly affect the alveoli of the lungs.
