Differential Diagnosis for Right Upper Expiratory Wheezing in the Right Upper Lobe
- Single most likely diagnosis + Asthma: This is a common condition that can cause wheezing, particularly if it's localized to one area of the lung. The right upper lobe wheezing could be due to asthma that is not well-controlled or is exacerbated by specific triggers.
- Other Likely diagnoses + Chronic Obstructive Pulmonary Disease (COPD): COPD can cause wheezing, especially in smokers or those with a history of smoking. The wheezing may be more pronounced in certain areas of the lung, such as the right upper lobe. + Bronchitis: Acute or chronic bronchitis can cause wheezing due to inflammation of the airways. If the bronchitis is localized to the right upper lobe, it could explain the symptoms. + Pneumonia: Pneumonia, especially if it's localized to the right upper lobe, can cause wheezing due to the inflammation and congestion in the lung tissue.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.) + Pulmonary Embolism: Although less common, a pulmonary embolism can cause sudden onset of wheezing, particularly if it's localized to one area of the lung. This is a life-threatening condition that requires immediate attention. + Lung Cancer: In rare cases, lung cancer can cause wheezing, especially if a tumor is obstructing an airway. This is more likely in smokers or those with a history of smoking.
- Rare diagnoses + Cystic Fibrosis: This genetic disorder can cause chronic respiratory symptoms, including wheezing, due to the production of thick mucus that clogs the airways. + Bronchiectasis: This condition involves the permanent enlargement of parts of the airways and can cause chronic wheezing, particularly if it's localized to one area of the lung. + Foreign Body Aspiration: If a foreign object is lodged in the airway, it can cause wheezing, particularly if it's obstructing the right upper lobe. This is more common in children but can occur in adults as well.
