Delayed diagnosis of multiple magnet ingestion in a pediatric patient led to intestinal perforation requiring surgical resection, highlighting the risks associated with missed or misinterpreted foreign body ingestion, according to a case report published in Cureus.
Foreign body ingestion is common in pediatric patients, particularly those younger than 6 years. While most ingested objects pass spontaneously through the gastrointestinal tract, ingestion of multiple magnets poses a unique risk because of their ability to attract across bowel walls, leading to tissue injury and serious complications.
The case report involved a 4-year-old boy who presented with recurrent abdominal pain lasting approximately 1 year. At an earlier evaluation, abdominal imaging had been misinterpreted as showing an external artifact rather than a foreign body, delaying diagnosis and treatment.
Upon re-evaluation, imaging revealed a chain of radiopaque, bead-like foreign bodies in the lower abdomen, which were later confirmed at surgery to be multiple magnets.
Surgical exploration identified 22 magnetic pieces forming a closed loop within the bowel. The magnets had caused pressure necrosis and small bowel perforation, necessitating resection of a 15-cm segment of the mid-jejunum followed by anastomosis. The patient recovered well and was discharged 4 days postoperatively. At 3-month follow-up, he had no complaints.
Multiple magnet ingestion is particularly dangerous because magnets can attract across different loops of the intestine, causing sustained compression. This process may result in ischemia, necrosis, obstruction, fistula formation, or perforation of intervening intestinal walls.
Diagnosis can be challenging, as symptoms are often nonspecific, including intermittent abdominal pain without clear signs of obstruction or infection. Additionally, multiple magnets may cluster together on imaging and be mistaken for a single object or artifact, as occurred in this case.
The authors noted that management depends on the number and location of the magnets as well as symptom severity. Asymptomatic patients may be monitored with serial imaging, whereas symptomatic patients or those with multiple magnets beyond the stomach warrant prompt specialist evaluation. Early intervention, particularly when magnets are still accessible, may help reduce the risk of severe complications.
In conclusion, the authors highlighted the importance of maintaining a high index of suspicion and performing careful radiologic assessment in pediatric patients presenting with unexplained gastrointestinal symptoms. Risk appears to be greatest in boys, in children younger than 6 years, and in those with behavioral, neurodevelopmental, or psychiatric conditions, including pica. Early consideration of foreign body ingestion may help prevent delays in diagnosis and reduce the risk of serious complications.
