Paediatric trauma with hyperamylasemia. In this case report, we describe a paediatric case of hyperamylasemia following parotid trauma. A 12-year-old boy was hit by a motorcycle, sustaining only superficial lacerations to the face overlying the parotid. A hyperamylasemia was noted, and further characterised by a fractionated isoamylase test, as being predominantly of the salivary type. Serum lipase levels were low. Based on these investigations, pancreatic injury was judged unlikely with the minor parotid trauma being the probable source of the hyperamylasemia. The patient was spared further unnecessary investigations and managed conservatively.
