Lung damage due to low-voltage electrical injury

Abstract

Contact with high- or low-voltage electricity can cause injury. Low-voltage damage is more common and widespread, although there is little information on it in the literature. Exposure to an electrical current can effect every organ system in the body. The degree of damage is related to many factors, including the duration of exposure, type of current, and nature of the affected tissue. An unusual low-voltage electrical injury with a serious pulmonary lesion is presented, including the clinical intervention and imaging findings. We present a 20-year-old male electrician who sustained direct electrical damage to the pulmonary parenchyma, with no signs of chest wall damage, when exposed to a 380 V shock while working. Imaging demonstrated an electrical burn of the posterior right lower lobe. This case demonstrates that a low-voltage electric current can cause lung damage. A timely diagnosis is required for treatment.
