CT in Penetrating Wooden Foreign Bodies of Head and Neck

공기음영으로 오인될 수 있는 두경부 영역의 관통성 나무이물에 대한 컴퓨터 전산화 단층촬영의 의의

Retained wooden foreign bodies following penetrating trauma are a difficult diagnostic problem. However, penetrating wooden foreign bodies of head and neck have the potential for misinterpretation or failure to detect such foreign bodies on CT. Given the likelihood that such a miss will result in an abscess or neurovascular injury, we present the method with higher window settings, they had a higher attenuation with a unique striated internal architecture and different Hounsfield numbers readily differentiate air and non-air hypodense material such as fat, or possibly wood. Being aware of the potential appearance of wood, we may also find CT useful in excluding small retained fragments in postoperative patients with persistent symptoms. This article presents two cases in which wooden foreign bodies of head and neck were present with CT evaluation.
