can more accurately depict the oblique defect or indentation along the posterior esophageal wall.
demonstrated contrast leakage in the ipsilateral cervical openings via tracts from the bilateral tonsillar fossae (figure, B).
During surgery, esophagography
showed no anastomotic leaks.
The esophagus has traditionally been examined in great detail by contrast fluoroscopy or endoscopy, and subtle pathology may potentially be missed when depending on CT for screening evaluation without the mucosal detail provided by contrast esophagography
The survey radiographs confirmed that there was soft tissue density in the midcervical region but not conclusive for perforation or fistula but esophagography
helped to confirm esophageal fistula as reported earlier by Kasari (1984).
is useful in identifying the perforation when extravasation of hydrosoluble contrast material occurs allowing also establishing if the leak is contained or not .
Esophageal perforation can be diagnosed with esophagography
, esophagoscopy or Computed tomography.
was performed because of the suspicion of esophageal perforation, and it detected a distal end esophageal perforation.
In our case, exclusion of the diseases in the differential diagnosis through a detailed clinical evaluation with video laryngoscopy and imaging modalities, such as radiography, esophagography
, CT, and MRI, confirmed that the reason of the dysphagia was osteophytes.
and gastroesophageal reflux scintigraphy, respiratory function test, and high-resolution computed tomography results were also normal.
Other diagnostic tools to detect perforation of esophagus include esophagography
with Barium and CT-Scan of thorax  and their application is to determine discharge of food particles and billium from pleural space into mediastinum .
