(a) Skull radiograph, frontal view, showing the missing denture from the right lower jaw (white arrow). (b) Thoracoscopically removed partial denture. (c, d) Anteroposterior and lateral view chest radiographs showing a metallic density foreign body in the retrocardiac region (white arrows), pneumomediastinum (arrowhead) and subcutaneous emphysema (yellow star).

The denture (Figure 1b) was removed and the oesophageal tear was repaired subsequently.
(a, b) Plain CT scan of the chest in coronal section showing a metallic density foreign body (white arrows) in the middle one-third of the oesophagus. (c) Axial non-contrast-enhanced CT scan showing pneumomediastinum (yellow star), subcutaneous emphysema (blue arrow) and left pneumothorax.

On the CT scan, two metallic density objects (measuring approximately 17 mm each) were seen in the middle one-third of the oesophagus (Figure 2a,b), with a suspicious contained leak of orally ingested positive contrast media along the right posterolateral aspect of the oesophagus (Figure 3a). In addition, there was pneumomediastinum with left pneumothorax and subcutaneous emphysema of the neck and chest, which confirmed the diagnosis of oesophageal perforation secondary to ingested dentures (Figure 2c).
(a) Saggital plain CT scan of the chest with positive oral contrast; white arrows showing contrast column in the oesophagus; blue arrow showing metallic denture in the retrocardiac location; yellow arrowhead showing the leak of positive oral contrast at the site of the second denture fragment. (b, c) Post-operative seventh day plain coronal CT scan of the chest and gastrograffin study showing no leak in the repaired oesophagus with resolution of pneumothorax and subcutaneous emphysema.

On the CT scan, two metallic density objects (measuring approximately 17 mm each) were seen in the middle one-third of the oesophagus (Figure 2a,b), with a suspicious contained leak of orally ingested positive contrast media along the right posterolateral aspect of the oesophagus (Figure 3a). Per oral diet was then started gradually (Figure 3b,c).
