Abstract
We report a case in which iodinated oil (lipiodol ultra-fluid (UF)) leaked from an iatrogenic perforation of Stensen's duct and constituted a foreign body in the cheek. The distribution of contrast medium near the lower border of the mandible seems unusual. 2 years following sialography, the UF was still not being resorbed. No radiological signs of reactive inflammatory changes to the soft tissue were observed. We believe the contrast agent arrived beneath the skin, but external to the platysma, through a simple perforation in either the duct and/or the mucosa.
