This report concerns two brothers aged 10 and 18 years with long-standing dysphagia that started at age three and six years respectively. They had been diagnosed as achalasia and treated accordingly. The appearance of additional symptoms and clinical signs required further investigations including abdominal sonography, esophago-gastroduodenoscopy, barium swallow, esophageal manometry, computerized tomography (CT) of abdomen and brain, biochemical profiles, and neurologic and ophthalmic evaluations.
