Computed tomography enterography reconstruction (a) reveals extensive alteration of the small loops, both the distal jejunum and ileum, including the last ileal loop and ileocecal valve, for at least 140 cm. The ileocecal valve is poorly identifiable. Immediately upstream, further ileal loops are observed with thickened walls (maximum thickness 10 mm) with an extension of approximately 30 cm and a lumen of reduced caliber (3 mm). The ileum upstream and distal jejunum have at least eight pathological tracts with thickened walls (maximum thickness 7 mm), with a longitudinal extension varying from 2 to 6 cm, and reduced caliber (residual lumen of 4 mm), alternating with tracts of normal or slightly increased caliber (maximum caliber: 25 mm). These alterations are also associated with hypervascularization, increased density of adipose tissue, and reactive lymph nodes in the mesentery. (b) At the request of the surgeon, the healthy intestine was measured and was approximately 70 cm.
