==Complete Differential Diagnosis of Underlying Causes of Pneumothorax==
==Overview==
'''Causes'''
Pneumothorax must be differentiated from other diseases that cause shortness of breath, difficulty breathing, and chest pain, such as [differential dx1], [differential dx2], and [differential dx3].

==Differential Diagnosis of Conditions that Pneumothorax must be Distinguished From==
! style="background: #F5F5F5; padding: 5px;" |-
*[[Myocardial infarction|Acute Myocardial Infarction]]: presents with shortness of breath and chest pain, though MI chest pain is characteristically crushing, central and radiating to the jaw, left arm or stomach.   While not a lung condition, patients having an MI often happen to also have lung disease.
! style="background: #F5F5F5; padding: 5px;" |+
*[[Emphysema]]: here, delicate functional lung tissue is lost and replaced with air spaces, giving shortness of breath, and decreased air entry and increased resonance on examination.   However, it is usually a chronic condition, and signs are diffuse (not localised as in pneumothorax).  
! style="background: #F5F5F5; padding: 5px;" |-

A careful history, physical examination and a chest x-ray will allow the conditions to be differentiated.
