title: Tornwaldt's cyst: clinical and radiological aspects.
abstract: Tornwaldt's bursae or nasopharyngeal bursae originate at the interface between the embryonic tissue from which the vertebrae develop (the notochord), and the developing foregut. If the opening through which the bursa drains into the nasopharynx becomes obstructed, a Tornwaldt's cyst will develop. The history, clinical and radiological findings and the operative management of a patient with an infected Tornwaldt's cyst are presented.
