A man aged 30 years presented to an emergency department with a 1 month history of severe abdominal pain, jaundice, constipation, lower extremity weakness and weight loss. A peripheral blood smear was performed that showed basophilic stippling of erythrocytes prompting a blood lead level (BLL) evaluation. The patient had a BLL of >200 µg/dL. Retained bullet fragments were identified in the left lower extremity from a previous gunshot wound 10 years prior. Lead from the excised bullet fragment was consistent with the patient's blood lead by isotope ratio analysis. This case is a rare example of a severely elevated BLL attributed to bullet fragments in soft tissue. Bullets retained in soft tissue are not often considered a risk factor for a markedly elevated BLL because they become encapsulated within the tissue over time.
一名30岁男性因严重腹痛、黄疸、便秘、下肢无力和体重减轻1个月就诊于急诊科。进行了外周血涂片检查,结果显示红细胞嗜碱性点彩,促使对血铅水平(BLL)进行评估。该患者的血铅水平>200µg/dL。在左下肢发现了10年前枪伤残留的子弹碎片。通过同位素比率分析,切除的子弹碎片中的铅与患者的血铅相符。该病例是软组织中子弹碎片导致血铅水平严重升高的罕见例子。软组织中残留的子弹通常不被视为血铅水平显著升高的危险因素,因为随着时间的推移它们会被组织包裹起来。
