Appearance of CT scan acquired before and after cefmetazole plus levofloxacin treatment, i.e., on day 15 and day 30 after admission. The CT scan acquired before using cefmetazole plus levofloxacin treatment (1A, 1B) showed a multilocular low-density shadow in the right iliopsoas muscle (white arrows in 1A), and a high-density shadow with newly formed cavitation in the right lung (white arrow in 1B), suggesting multiple abscess formation. The CT scan acquired after 12 days of cefmetazole plus levofloxacin (1C, 1D) showed that both the right iliac muscle (white arrows in 1C) and right lung (white arrow in 1D) abscesses had decreased in size
