Introduction: Lead poisoning in childhood remains an important public health concern. We highlight the radiological findings in a patient with a high blood lead concentration.
Case summary: A 7-year-old girl presented to hospital with abdominal pain, nausea, and asthenia. Laboratory tests showed severe hypochromic microcytic anemia, punctate basophilic stippling of erythrocytes, and a blood lead concentration of 880 µg/L (4.3 µmol/L).
Images: Radiographs of the femur, tibia, and fibula demonstrated dense metaphyseal bands ("lead lines"). On cranial computed tomography, we observed multiple speck-like and curvilinear hyperdensities involving subcortical regions, putamen, and left cerebellar hemisphere.
Conclusion: In patients with lead poisoning, imaging of the brain and bones may show characteristic features. These imaging findings may point to the diagnosis of lead toxicity when these radiographic findings are discovered during the evaluation of vague complaints such as abdominal pain or mental status changes or when a blood lead concentration is not readily available.
