Etiology and management of spontaneous haemothorax.

Spontaneous haemothorax (SH) is a subcategory of haemothorax that involves the accumulation of blood within the pleural space in the abscence of trauma or other causes. The clinical presentation is variable and includes a rapid progression of symptoms of chest pain and dyspnea that can be life threatening when hemodynamic instability and hypovolemic shock occurs. Despite haemothorax, SH is much less common with data limited to case reports and case series. A literature review has been performed to identify and summarise all potentials causes leading to this clinical entity.
