An Unusual Pattern Of Post-Traumatic Subcutaneous Emphysema Of The Neck, Chest And Abdominal Wall

Abstract

Motor vehicle accidents are a major health concern in both developed and developing countries. These result in varying degrees of morbidity and even death. There are many causes of subcutaneous emphysema. Most cases of subcutaneous emphysema encountered in clinical practice are iatrogenic. These are usually secondary to procedures. Traumatic causes as a result of blunt or penetrating injuries is a known aetiology. An unusual case of massive subcutaneous emphysema involving the neck, chest, and abdominal wall following traumatic rib fracture, with associated pneumothorax, pneumomediastinum, and prevertebral soft tissue air, is presented. Chest x-ray examination alone may not be sufficient in investigating these patients, as other associated conditions may not be shown with this imaging modality. The importance of computed tomography (CT) in evaluating this condition is highlighted. The prompt CT examination established the extent of the soft tissue air and the other associated abnormalities; and this contributed remarkably to the favourable outcome in this case presented.
