Panel A: September 2025 contrast‑enhanced abdominal CT shows focal thickening of the ileocecal intestinal wall. Neoplastic lesion is highly suspected, while intestinal tuberculosis cannot be excluded clinically. Panel B: Postoperative HE‑stained histopathology (×10) identifies moderately‑differentiated ascending colon adenocarcinoma invading the intestinal serosal layer. — (A) Contrast-enhanced whole-abdominal CT scan in September 2025, showed focal thickening of the ileocecal intestinal wall. Neoplastic lesion was considered the primary diagnosis, and the possibility of intestinal tuberculosis could not be excluded in combination with the patient’s medical history. (B) Postoperative pathology (HE staining, ×10 magnification) revealed moderately differentiated adenocarcinoma of the ascending colon, with the lesion invading the serosal layer.
