Bilateral Renal Infarcts Due to Blunt Trauma in a Healthy Young Female Patient: A Case Report

Bilateral renal infarcts due to blunt trauma in the absence of underlying pathology are a rare condition. Trauma-induced renal infarction occurs due to decreased perfusion to the renal system. A 23-year-old woman with no significant past medical history presented to the emergency department with abdominal pain after being struck by a car as a pedestrian. She reported abdominal pain, shoulder pain, and pelvic pain. Imaging revealed multiple traumatic injuries, including a right shoulder dislocation, vertebral and pelvic fractures, and bilateral renal infarcts. Extensive workup, including echocardiography, renal ultrasound, magnetic resonance angiography, and hypercoagulability testing, was unremarkable. The findings were attributed to transient renal hypoperfusion secondary to trauma-related vascular dysfunction. Her symptoms resolved with conservative management, and she was discharged with outpatient follow-up. Renal infarcts are most commonly due to cardioembolic events, and trauma-induced renal infarcts are rare and typically result from hypoperfusion, vasospasm, or vascular injury. Contrast-enhanced CT imaging is used to diagnose renal infarcts. Most trauma-related cases of renal infarcts resolve spontaneously without any complications. This case highlights a rare instance of bilateral renal infarction after blunt abdominal trauma. Further research is warranted to discuss the clinical significance of and long-term outcomes of transient renal hypoperfusion in trauma patients.
