Location mapping and horizontal CT of the trachea and bronchi revealed two round high-density shadows (red arrow) of diameter ~0.5 cm that appeared to be located in the upper part of the trachea at the level of the chest (A,B). A residual round, metallic, foreign body shadow was apparent at the entrance of the thoracic cage on chest frontal and lateral DR performed at 6 h post-operatively (C,D).

Post-operative chest and abdominal digital radiography (DR) performed on the same day at 2:35 p.m. revealed a residual round, metallic, foreign body shadow at the entrance of the thoracic cage on chest frontal and lateral DR (Figures 1C,D).

Post-operative chest and abdominal digital radiography (DR) performed on the same day at 2:35 p.m. revealed a residual round, metallic, foreign body shadow at the entrance of the thoracic cage on chest frontal and lateral DR (Figures 1C,D).
Abdominal DR indicated no obvious abnormality at 6 h post-operatively (A). Chest DR re-examination indicated that the foreign body shadow had disappeared before the planned second operation (B). The blue and purple magnetic beads were magnetically attracted (C). Abdominal DR re-examination indicated no obvious, remaining, foreign body shadow after the second foreign body had been expelled (D).

The two balls were magnetically attracted (Figure 2C). Abdominal DR re-examination on the same day (Figure 2D) indicated no obvious, remaining, foreign body shadow.
