“…Other studies also described intestinal obstruction from internal hernia and volvulus of intestine, fistula formation [10], and hemorrhage when the mesenteric was involved [10]. Midget J reported a twenty-month old boy who had ingested magnets, causing intestinal necrosis and abdominal sepsis, which led to death [11,12]. Additionally, Waters AM [13] reported another case of death due to the hemorrhage from an esophago-aortic fistula induced by ingestion of magnets.…”

“…Another investigation in 2013 reported that during 2002 and 2011, there had been more than 22,000 pediatric magnetic foreign body ingestion cases in America, and the investigation showed a 5-fold increase comparing the first and the last 2 years [4]. Rare-earth magnet, made from NdFeB (neodymium iron boron), a newly developed magnetic material, has a maximum magnetic energy force 5 to 10 times than that of the ordinary ferrite [12,15,16], suggesting that the tiny rare-earth magnet can produce a huge magnetic force. It was primarily developed for industrial Gastrointestinal mucosa erosion 28 37.8 -manufacturation such as electrical machinery, medical apparatus and instruments, in order to decrease the volume of production and enlarge its properties.…”

Purpose: To describe the incidence and management of gastrointestinal tract Buckyball magnets ingestions in a multicenter Chinese pediatric patient population, and discuss the preventive measures. Methods: Medical records of 74 pediatric patients from 9 large Chinese hospitals during the past 10 years, who were diagnosed as buckyball magnets ingestion and got invasive treatment, were retrospectively studied. The follow-up was through telephone and outpatient service to estimate the post-surgery condition. Information collection was through online questionnaire. Results: Among the 74 cases, there were 50 boys (68%) and 24 girls (32%). The median age was 36 (interquartile range (IQR) 22-77) months, with a range of 7 months to 11 years, and it showed two peaks, the first between 1 and 3 years, and the second between 6 to 11 years. The annual case number showed a sharp increase over time, and the total case number in the last 2 years (2017 and 2018) showed a greater than 9-fold increase when compared with the first 2 years (2013 and 2014). The majority of ingestions were unintentional, with only 3 patients deliberately swallowing the Buckyball magnets. The median time of ingestion until the onset of emergent symptoms was 2 (IQR 1-5) days, and ranged from 4 h to 40 days. Twenty-one patients had no symptoms, and the remaining cases presented with abdominal pain, vomiting, fever, abdominal distension, excessive crying, melena, and the ceasing of flatus and defecation. Gastroscopy, colonoscopy, laparoscopic surgery and laparotomy surgery were performed in accordance with the algorithm from the North American Society of Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN). Procedural and operative findings included gastrointestinal mucosa erosion, ischemia and necrosis, perforation, and abdominal abscess, fistula and intestinal obstruction. The median number of Buckyball magnets ingested was 4 (IQR 2-8), with a range from 1 to 39. During the median follow-up period of 6 (IQR 1-15) months, 3 patients had intestinal obstruction, and one underwent a second operation. The remaining 71 patients courses were uneventful during the follow-up period. None of the 74 patients reported a second swallowing of foreign bodies. Conclusions: The incidence of pediatric gastrointestinal tract magnets ingestion in China is increasing. Management of such patients should follow the NASPGHAN algorithm. Preventive measures to limit children's access to Buckyball magnets should be taken from three levels, namely the national administration, producer, and consumer.

“…A particularly dangerous subset of magnets is small rare-earth magnets such as neodymium magnets, which are substantially stronger than traditional ferrite magnets [3,4]. Ingestion of multiple of these "supermagnets" is of special concern, as they can attract through intestinal walls, resulting in pressure necrosis, fistulization, and bowel perforation [5][6][7].…”

Background and Aim. Rare-earth magnet ingestions are a subset of foreign body ingestions and can result in significant morbidity secondary to pressure necrosis. These magnets are best visualized radiographically, typically located in the gastrointestinal tract. However, unusual locations of magnetic adherence may include the hypopharynx along the epiglottis, where only 2 previous cases have been reported. Clinicians should be aware of the potential dangers of rare-earth magnet ingestion and consider atypical locations of attachment in the appropriate clinical setting. Case Presentation. We present an interesting case of a fourteen-year-old female patient who presents with witnessed ingestion of multiple rare-earth magnets. Soft-tissue neck radiographs demonstrate two adjacent rounded radiopaque densities in the hypopharynx. Intraoperative images confirmed the radiographic findings and identified two magnetic balls stuck along the dorsal and ventral aspect of the epiglottis without evidence of pressure necrosis. Conclusion. This is the first published case of magnetic foreign body adherence to the epiglottis in the Radiology literature. Awareness and recognition of the unique radiographic findings of this rare entity can help clinicians streamline timely management.
