case_images: Abdominal computed tomography (CT) findings showed uneven thickening of the terminal ileum (Figure 1).
case_images: Pathological image of surgical specimens. (A) H&E. (B) CD99. (C) Detection of EWSR1 gene disruption by FISH. The probe type: Vysis LSI EWSR1 Probe (LOT 455960). Result of the patient's EWSR1 gene disruption test: positive (count 200 cells, approximately 90% show separation signal). FISH, fluorescence in situ hybridization.

case_images: Stunningly high levels of PCT, which lasted nearly 100 days in the absence of infection, dropped almost a hundredfold after one operation (Figure 3).
case_images: Preoperative and postoperative contrast-enhanced MRI of the abdomen. Preoperative (A) coronal and (C) transverse sections. Postoperative (B) coronal and (D) transverse sections.
