case_images: (a) Initial chest computed tomography (CT) showed no obvious abnormal findings. (b) No air in the esophagus was seen on CT 2 months after onset (asterisk).

case_images: The first chest computed tomography (CT) was interpreted as normal [Figure 1a]. Esophageal stricture and thoracic vertebra OVF were suspected based on the results of the second chest CT [Figure 1b].
case_images: (a) Thoracic magnetic resonance imaging showed low intensity on T1WI and isointensity on T2WI at T7. (b) Thoracic kyphosis deformity was seen on thoracic spinal computed tomography after 2 months of initial onset.

case_images: T7 OVF with a kyphotic deformity [Figure 2]. Twice, she underwent esophagogastroscopy that showed no obstruction.
case_images: (a) Intraoperative balloon kyphoplasty (BKP) findings were correctable from 22.4 to 17 agrees. (b) Thoracic spine computed tomography after BKP surgery showed intraesophageal air (asterisk) was also confirmed.

case_images: As her symptoms were attributed, therefore, to the T7 OVF, she underwent a T7 BKP resulting in an improved kyphotic angle from 22.4 degrees to 17 degrees [Figure 3].
