Nowadays, lead poisoning in children commonly occurs, but lead poisoning caused by the administration of Tibetan medicine is rarely reported. This report describes the diagnosis and management of lead poisoning in a 16-year-old girl presented with abdominal pain, vomiting, and anemia with limb numbness, who had a childhood history of epilepsy and took Tibetan medicine intermittently to control the symptoms. After admission into hospital, Computed tomography showed high-density shadows in the gastrointestinal tract. Video-Electroencephalography showed no signs of seizure. Reflux esophagitis was observed in gastroscopy. And no obvious abnormalities in the colonic mucosa through colonoscopy. Bone marrow smear test showed basophilic stippling in the erythrocytes. The blood and urine lead levels of 626 and 75.9 μg/L, respectively. We therefore considered lead poisoning, and the patient improved after chelation therapy. Due to its atypical clinical manifestations, lead poisoning is easily misdiagnosed. Thus, clinicians should pay more attention to this disease. When abdominal pain, anemia, and neurological symptoms are present, the possibility of lead poisoning should be considered.
