Abdominal tomography demonstrated coarse calcifications associated with the previous operation in the posterior aspect of the left liver lobe along with a heterogenous and solid area of 11 x 6 cm in size showing mild enhancement after intravenous contrast administration around which the adjacent adipose tissue had a streaky appearance (Figure 2).
Barium small bowel passage radiogram displaying marked wall thickening involving a 40 cm long segment adjacent to the terminal ileum, characterized by displacement of the adjacent intestinal loops. No luminal irregularity, narrowing, or cavity formation was observed. These findings were interpreted as terminal ileal involvement of Crohn's disease.
