Effective Use of Computed Tomography for Detection of Press-Through-Package Sheet Ingestion in a Pediatric Patient.

: Press-through-package sheet (PTPS) ingestion can cause perforation of gastrointestinal tract. Such incidents, which require immediate medical attention, are often observed in elderly people. In this report, we describe the case of a 12-year-old patient who ingested PTPS. The patient, who has attention-deficit/hyperactivity disorder, presented with abdominal pain at our hospital. While it was not revealed by a chest x-ray, computed tomography scan showed a PTPS lodged in his lower esophagus. The ingested PTPS was removed by endoscopy without complications. Press-through-package sheets ingestion can occur in pediatric patients, and computed tomography scan is useful in the diagnosis.
