A. Posterior-anterior radiograph of the skull depicting the round and pellet-like radiopaque foreign body of the left orbital region and the radiopaque screw-shaped foreign body of the left paravertebral. B. Lateral radiograph of the skull indicates the position of orbital foreign body close to the infraorbital rim and the parapharyngeal screw caudal and slightly anterior to the mastoid. C. Detail of the en-face view shows that there is no visible scar indicating the entrance of the foreign body.

Physical examination of the patient revealed a firm and slightly moveable foreign body of the left medial eye lid's angle, covered by an unaffected skin (Figure 1C (Fig. 1)).
A. Ultrasonogram of the orbital foreign body. The skin-to-object distance is about 5 mm. The hemispheric diameter is about 9 mm. B. Ultrasonogram of the left parapharyngeal space reveals an ultrasound remitting surface in an oblique position to the surface of the applicator. Proximal to the applicator and covering the surface is a concave hypoechoic zone (arrow). C. The foreign bodies (left: airgun pellet, right: screw) and the fibrous bag that covered the screw (left below) with millimetre scale (total length of screw: 30 mm; diameter of screw head: 12 mm; pellet diameter: 9 mm).

It was suggested that the foreign body was an air gun pellet (Figure 2A (Fig. 2)). In the left neck the foreign body was identified anterior and medial to the sternocleidomastoid muscle (Figure 2B (Fig. 2)). It was completely removed with this capsule (Figure 2C (Fig. 2)).
