What medical condition does the abbreviation PTX expand to?

• A. Pneumonia
• B. Pleural Effusion
• C. Pulmonary Edema
• D. Pneumothorax

Answer: (D)

PTX expands to pneumothorax, a condition where air collects in the pleural space—the gap between the lung and chest wall—causing the lung to partially or completely collapse. This shorthand is widely used in clinical notes and imaging reports to indicate air in that space. It’s different from pneumonia, which is an infection of lung tissue; pleural effusion, which is fluid in the pleural space; and pulmonary edema, which is fluid buildup inside the lungs. Because PTX specifically refers to air in the pleural space, it is the correct expansion for this abbreviation.
