Due to the specific features of the adrenal glands, traumatic adrenal injury is a rare phenomenon. The majority of these rare types of traumas are caused by blunt force injuries and rarely by penetrating mechanisms. In such cases, a whole-body computed tomography scan is essential for early diagnosis. This paper describes an uncommon case of adrenal hematoma and contusion followed by blunt abdominal trauma. A 35-year-old woman was admitted to the emergency department after a high-speed vehicle-pedestrian collision. She presented with decreasing level of consciousness. Additionally, a thoracoabdominal CT scan revealed a left flank hematoma. Blunt adrenal injury, often accompanied by multiorgan damage, is a rare occurrence resulting from severe accidents. Accurate diagnosis based on clinical symptoms requires high clinical suspicion, particularly in isolated cases, and treatment depends on the patient's condition.
