Nonenhanced CT (NECT) (Figure 1(a)) demonstrated a poorly demarcated mass with two sharp linear calcifications, and contrast-enhanced CT (CECT) (Figure 1(b)) showed a heterogeneously enhancing mass with a small abscess pocket in the right anterior cervical space near the midline, between the platysma and strap muscles. The mass appeared to invade into the right strap muscle (Figure 1(b)).

At operation, an about 3 x 3 cm sized irregular mass with solid and cystic components that adhered severely to the adjacent structures was noted (Figure 2(a)). Two sharp linear fishbone foreign bodies were identified within the mass (Figure 2(a)). Pathologic findings of the excised specimen were consistent with fishbone-associated actinomycosis (Figure 2(b)).
