The case of a 20-year-old female prisoner who died due to cardiac tamponade caused by a swallowed sewing needle migration is reported. According to the autopsy report and complete analysis of medical records, the migration of the swallowed needle was reconstructed: from esophagus and stomach, through diaphragm and pericardium up to the left heart ventricle, where the needle was found at the autopsy. The case is very interesting and unique: there has been no similar case described in medical literature so far.
