title: Esophageal dischalasia: serendipity during 99mTc thyroid scan.
abstract: It is rare for a large amount of pooled radioactive saliva to be observed in the neck during a thyroid scan. Such a finding would imply abnormal salivation and/or esophageal kinesis. The case of esophageal dischalasia reported here suggests that a complete study of the esophagus is advisable when a large area or amount of radioactive saliva is observed in the neck during a thyroid scan.
