title: Occult traumatic loculated tension pneumothorax--a sonographic diagnostic dilemma.
abstract: This case outlines a rarely seen disease in prehospital emergency care-namely, a traumatic loculated tension pneumothorax. Prehospital thoracic ultrasound as part of a standard extended focused assessment with sonography in trauma (EFAST) algorithm failed to diagnose this life-threatening injury. We have subsequently added scanning the lateral chest wall in the fifth intercostal space to the algorithm.
