From the Research
The primary causes of a collapsed lower lobe are atelectasis, pneumonia, pleural effusion, pulmonary embolism, lung cancer, and trauma, with atelectasis being the most common cause. These conditions can lead to a range of complications, including respiratory failure, which can significantly impact morbidity, mortality, and quality of life. The provided evidence does not directly address the causes of a collapsed lower lobe, as it focuses on the effects of cyproterone acetate on growth and endocrine function in precocious puberty 1. However, in real-life clinical practice, it is essential to consider the most common and severe causes of a collapsed lower lobe, such as:
- Atelectasis, which can occur due to airway obstruction by mucus plugs, foreign bodies, or tumors
- Pneumonia, which can cause inflammation and fluid accumulation in the alveoli
- Pleural effusion, which can compress the lung from outside
- Pulmonary embolism, which can decrease blood flow and surfactant production
- Lung cancer, which can directly obstruct airways or compress lung tissue
- Trauma, including rib fractures or pneumothorax, which can also lead to lower lobe collapse. Treatment should be tailored to the underlying cause, with a focus on preventing complications and improving quality of life.
