CT - Abdominopelvic with contrast
Redemonstration reveals the persistently thickened ileal wall without an abrupt transition site. The thickened intestinal wall also exhibits small cystic central areas without contrast medium uptake, corresponding to regions of necrosis. The intestinal wall has an average diameter of 3.0 cm, and multiple lymph nodes are also noted.
The liver displays diffuse heterogeneous enhancement, likely due to the late-stage images. Subsequent ultrasound and staging CT scans show no evidence of lesions suggestive of metastasis.
