Man With Accidentally Swallowed Dental C+ File

A 32-year-old man presented to the dentist to receive root canal therapy. During the treatment, a C+ file dropped and was accidentally swallowed by the patient. No foreign body was found by emergency gastroscopy that day. The next day, abdominal radiograph showed a cross-shaped high-density shadow in the lower right abdomen (Figure 1, arrow) and the shadow did not move obviously in the radiographic reexaminations during the following 3 days. The patient did not complain of any discomfort. On the fifth day, computed tomography (CT) of the abdomen and pelvis indicated a hyperdense structure located in the ileocecal region (Figures 2 and 3, arrow).
