Gastroesophageal squamocolumnar junction - Ganzer Fall bei Radiopaedia
The Z line in the esophagus is the term for a faint zig-zag impression at the gastro-esophageal junction that demarcates the transition between the stratified squamous epithelium in the esophagus and the intestinal epithelium of the gastric cardia (the squamocolumnar junction).
The Z line is a normal finding but is not seen in every study. An irregular or elevated Z line indicates potential distal esophageal metaplasia / Barrett esophagus, although the actual risk of this finding is debated.
