title: [Retropharyngeal hydatid cyst].
abstract: We report the case of a 37 year old male from rural area who presented as an emergency with symptoms compatible with the existence of a retropharyngeal tumoration. By the clinic it suggested an abscess but the CT scan as compatible with a carcinoma. On complementary examinations it appeared in a chest X ray an image which strongly suggested the possibility of a hydatidic cyst of the lung. Specific serologic reactions supported this and post-surgical pathological study lately confirmed the diagnosis. We believe of interest reporting this case because of it's unusual localization and difficulty in diagnosis.
