Rupture of the right hemidiaphragm due to blunt trauma

Five cases of right-sided rupture of the diaphragm are reviewed. Orthopedic injury, head injury, and shock were the most common associated findings. Apparent elevation of the right hemidiaphragm was seen initially in all cases, but two were misdiagnosed. An algorithm that includes modified peritoneal lavage, CT scan with contrast, and intraperitoneal Tc sulfur colloid is suggested for patients with suspected right diaphragmatic trauma.
