Difference Between Pulmonary Infiltrate and Effusion

Pulmonary infiltrates and effusions are both conditions that involve fluid in the lungs. While they may be easily confused, these two conditions are very different and can have different causes and treatments. In this article, we will discuss the differences between pulmonary infiltrates and effusions, and how to identify and treat each one.

What is Pulmonary Infiltrate?

Pulmonary infiltrate is an accumulation of fluid or cells in the lungs. This fluid or cells can be caused by anything from infection to cancer. In pneumonia and other infectious diseases, pulmonary infiltrate occurs when fluid builds up in the alveoli, the tiny sacs in the lungs where oxygen is exchanged. The infiltrate can also be caused by a foreign body, such as a tumor, or a reaction to a drug.

When pulmonary infiltrate occurs, it can cause coughing, difficulty breathing, and chest pain. However, it is possible for pulmonary infiltrate to be asymptomatic.

What is Pulmonary Effusion?

Pulmonary effusion is an accumulation of fluid in the pleural space of the lungs. The pleural space is the area between the two layers of the pleura, the tissue that surrounds the lungs. This fluid can be caused by infection, cancer, trauma, or other conditions.

When pulmonary effusion occurs, it can cause difficulty breathing, chest pain, and coughing. It may also cause a feeling of tightness in the chest.
