Abstract
BACKGROUND: Massive left hemothorax following left diaphragmatic and splenic rupture with visceral herniation is quite an uncommon life-threatening condition usually associated with blunt thoracoabdominal trauma. Mortality is generally associated with coexistent vascular and visceral injuries that could be rapidly fatal. Timely, and proper diagnosis is mandatory as survival depends on prompt diagnosis and treatment. PRESENTATION OF CASE: We describe a case of massive left hemothorax secondary to blunt thoracoabdominal injury with left diaphragmatic and splenic rupture, gastric, greater omentum and splenic herniation into the left thoracic cavity in a 32 years old male car driver after sustaining a road traffic accident and presented with shortness of breath of 4 h' duration. He also had zone 3 retroperitoneal hematoma and left acetabular fracture. He was treated surgically and discharged home improved. DISCUSSION: Diaphragmatic ruptures following blunt injuries are larger leading to herniation of visceral organs into the thoracic cavity and the most common organ to herniate on the left side is the stomach followed by omentum and small intestine. Splenic rupture is a very rare cause of hemothorax and is often missed in the differential diagnosis. CONCLUSION: Massive hemothorax following splenic and diaphragmatic rupture with visceral herniation following either blunt or penetrating trauma is rare. Delayed or missed diagnosis is associated with higher morbidity and mortality. A high index of suspicion and proper use of diagnostic studies are crucial for early and correct diagnosis.
