Foreign-body ingestion occurs frequently in childhood. The diagnosis of ingestion is usually made by plain film radiography. Ultrasound is not routinely used in the investigation of gastric foreign bodies because of the limitations imposed by intestinal gas. This drawback can be overcome by distending the stomach with an anechoic liquid, which acts as an acoustic window. In a child who had ingested a coin, US performed after drinking tea was diagnostic and showed a hyperechoic image with an acoustic shadow inside the stomach. We believe that US is an appropriate technique for follow-up of gastric foreign bodies.

Jejunal intussusception in a Chinese 10-year-old boy affected by the blue rubber bleb nevus syndrome is presented and discussed. The syndrome is rare, sporadically found with possible dominant inheritance, and due to a gene mutation mapped on the short arm of chromosome 9. It presents with distinctive cutaneous and gastrointestinal malformations together with possible other organ involvement. Gastrointestinal malformations tend to bleed and lead to anaemia. Infrequent complications of the gastrointestinal malformations are volvulus, intestinal infarction and intussusception. The age of the patient and the jejunal intussusception precipitated by a vascular malformation containing calcifications (which were also found in different gut segments) make this case remarkable.
