What are the typical imaging features of esophagitis on CT and MRI?
Segmental or diffuse smooth circumferential wall thickening of the esophagus is seen. Sometimes, increased mural enhancement, increased mural T2-weighted signal intensity relative to skeletal muscle, a “target” sign, luminal narrowing, surrounding fat stranding, intramural tract or abscess formation, or fistula formation between the esophagus and other structures such as the tracheobronchial tree or stomach may also be seen.
