Dislocation of the cervical oesophagus: a rare cause of oesophageal obstruction.

We describe a case of obstruction of the cervical oesophagus in which ultrasonography and computed tomography revealed characteristic dislocation of the cervical oesophagus and food impaction in a segmental canal. Although the patient presented with complete obstruction initially, spontaneous recovery of passage was achieved with conservative therapy. One recurrent episode was noted during her remaining life span. To our knowledge, no similar case has been described previously.
