title: Tornwaldt's cyst presenting only as occipital headache: a case report.
abstract: Tornwaldt's cyst (sometimes called Thornwaldt's cyst) is a rare cause of occipital headache. Owing to the rare occurrence of occipital headache as a symptom of Tornwaldt's cyst, if the patient presented only with occipital headache, this clinical symptom may be falsely perceived as a sign of neurologic disease leading to time-consuming diagnostic examinations that delay the establishment of a correct diagnosis.
