A: After conservative treatment, the C-reactive protein (CRP) level tended to decrease. However, the white blood cell (WBC) count increased to approximately 500, even at 2 weeks after the onset of appendicitis. Neut: neutrophil. B: This figure presents the findings of abdominal contrast-enhanced computed tomography of Case 2 at 23 days after the onset. The swelling of the appendix remained, and an amount of abscess formed in the liver (arrows).

The patient's abdominal findings gradually improved, and CRP demonstrated a decreasing trend (Figure 2-A). AML had not responded to chemotherapy and that the disease had progressed. Abdominal contrast-enhanced CT performed 23 days after the disease onset revealed residual inflammation of the appendix and a liver abscess (Figure 2-B).
