  Introduction Thoracic trauma remains one of the leading causes of preventable death worldwide. Among the various life-threatening injuries encountered in emergency departments, traumatic pneumothorax is particularly significant because delayed diagnosis can rapidly progress to respiratory failure, tension physiology, cardiovascular collapse, and death. Although computed tomography (CT) is considered the reference standard for diagnosing pneumothorax, trauma patients are frequently evaluated initially using portable supine chest radiography because of hemodynamic instability, immobilization, and the need for rapid bedside assessment. Unfortunately, diagnosing pneumothorax on supine chest radiographs is substantially more difficult than on upright radiographs. Free pleural air does not accumulate beneath the lung apex as expected in an upright patient. Instead, it migrates anteriorly, basally, and laterally due to gravity, producing subtle indirect radiographic signs that may be e...

  Introduction: A Silent Killer in the Supine Patient In the high-stakes environment of emergency medicine, few conditions demand as rapid and precise a diagnosis as supine tension pneumothorax . Unlike classic pneumothorax, where air accumulates in the pleural space and is often detectable via upright chest radiography, the supine variant presents a far more insidious diagnostic challenge. In trauma settings—particularly in intensive care units or among immobilized patients—this condition may progress rapidly, leading to cardiovascular collapse if not promptly identified. With the increasing reliance on CT scan diagnosis , advanced radiology interpretation , and emerging medical imaging AI , clinicians now have more powerful tools than ever to detect subtle imaging findings. This article provides a comprehensive, expert-level yet accessible review of supine tension pneumothorax, integrating clinical insights with radiologic expertise to support accurate emergency diagnosis .
