case_images: On the seventh hospital day, persistent abdominal pain prompted CT imaging of the abdomen, which revealed a 14x3.7x7.2 cm abscess along the medial wall of the left psoas muscle (Figure 1) and 2 additional abscesses at the L5-S1 level; 5.4x3.6 cm in the midline and 3.4x2.3 cm left of midline, and intramuscular air in the left gluteal muscles.
