Extrapleural haematoma (EPH) is a rare situation, which usually occurs due to rib fracture or blunt chest injury.
EPH results from accumulation of blood in the extrapleural space where the overlying extrapleural fat is displaced centrally.
- common: injury to intercostal arteries or veins
- less common: from other vessels such as aortic rupture, penetrating trauma and/or iatrogenic injury
May show a focal extrapleural collection in the appropriate clinical context with an extrapleural fat sign. They may be biconvex or nonconvex, with the former being larger.
Treatment and prognosis
Biconvex EPHs more often require surgical intervention, while non-convex haematomas are usually be managed conservatively 4.
