Abstract

"Pseudo" (or secondary) achalasia is a rare entity that it isn't easily distinguishing from idiopathic achalasia by manometry, radiological examination and endoscopy. Usually a neoplastic process of the esophago-gastric region is associated with this clinical condition. However, it has been reported that other neoplastic processes may lead to the development of pseudoachalasia, such as mediastinal masses, gastrointestinal tumours (pancreas, liver, biliary tract and other organs) and non gastrointestinal malignancies. We present a case of pseudoachalasia in which the primary cause of the disease was not an esophago-gastric cancer.
