case_images: Abdominal CT scan showing a hypo-absorptive area (red circle) of approximately 4 cm in diameter at the esophageal-jejunal anastomosis, suggesting an abscess.

case_images: Abdominal computed tomography showed a 40 mm hypodense solid mass at the site of the esophagojejunostomy (Figure 1).
case_images: Gram-stain of pus obtained by computed tomography-guided abdominal abscess drainage (a) and a positive anaerobic blood culture 20 hours after collection (b). The Gram-stain shows gram-negative rods with phagocytosis of leukemic cells in the pus obtained abdominal abscess (a) and gram-negative rods in the anaerobic blood culture (b) (magnification; x1000).

case_images: The following day, two aerobic blood culture bottles and pus obtained by CT-guided drainage confirmed the presence of gram-negative rods using Gram staining (Figure 2).

case_images: Two days of aerobic and anaerobic cultures of the blood and abscess confirmed only S. maltophilia, and hence, piperacillin/tazobactam was discontinued and the antibiotic was changed to SXT alone (Figure 3).
