Аннотация
INTRODUCTION: Coronary artery aneurysm (CAA) rupture is a rare but life-threatening condition that typically presents as acute coronary syndrome or with hemodynamic collapse. Distinguishing whether severe trauma is the primary event or secondary to a preceding medical catastrophe poses a significant diagnostic challenge in the emergency setting.
CASE PRESENTATION: An 85-year-old woman, found crouched on a street, was struck by a truck and was transported to the emergency department. On arrival, she was unconscious but hemodynamically stable. Contrast-enhanced computed tomography revealed a ruptured right coronary artery aneurysm with active extravasation and surrounding hematoma, along with multiple severe traumatic injuries, including subarachnoid hemorrhage and hemopneumothorax. The patient died several hours after aggressive resuscitation.
CONCLUSION: This case illustrates an extremely rare scenario where aneurysmal rupture likely preceded the traumatic event, leading to secondary blunt trauma. This emphasizes the critical importance of considering primary vascular emergencies as underlying causes in trauma patients who present with atypical findings.
