Abstract Secondary achalasia refers to the development of clinical, radiographic, and manometric findings of achalasia as a result of (i.e., secondary to) another underlying disorder. A variety of malignancies have been associated with secondary achalasia. Adenocarcinoma of the esophagogastric junction accounts for the majority of cases of malignancy-induced achalasia, however, noncontiguous tumors may also cause this disorder. Although rare, malignancy-induced achalasia will occasionally be encountered by gastroenterologists and gastrointestinal radiologists who see patients with dysphagia and/or achalasia. Since treatment is aimed at the underlying neoplasm, it is important to recognize this disorder. Three clinical features suggest the possibility of malignancy as a cause of achalasia: 1) short duration of dysphagia (〈1 year); 2) significant weight loss (〉15 pounds); and 3) age 〉55 years. The presence of any of these should at least raise a suspicion of malignancy. Diagnosis may not be evident on routine esophagrams and endoscopy, and requires clinical suspicion for further evaluation with thoraco-abdominal CT scanning and endoscopic ultrasonography.
