Successful preoperative identification of fish bone causing appendicitis using 3-dimensional multidetector-CT.

A 79 years male with fishbone-induced acute appendicitis was treated surgically with laparoscopic procedure. In preoperative diagnostic study, 3-dimensional multidetector-computed tomography (3D-MDCT) demonstrated the foreign body in the appendix and 3D-reconstructed images seemed fishbone with sharp-pointed dorsal fin directing to the tip of the appendix. With these findings, surgical indication of appendectomy was confirmed and laparoscopic appendectomy was performed. He made a full recovery and was discharged in a satisfactory condition following 7 days of post-operative treatment. From this case experience, 3D-MDCT seems helpful to visualize details of foreign bodies in the appendix, and valuable to confirm surgical indication of complicated acute appendicitis.
