[Hydatid cyst: another unusual localization].
We report a case of a 39-year-old woman who presented a right basicervical tumefaction. The chest X rays show a right cervicomediastinal opacity. Ultrasonography and computed tomography failed to describe the nature of the opacity. Because of the strong suspicion of neoplasm or a tuberculosis abscess, a needle aspiration of the cervical mass was performed and surprisingly revealed the presence of a cyst membrane allowing surgical resection.


CONCLUSIONS
Hydatid disease is a likely diagnosis in endemic areas in patients presenting a cystic mediastinal opacity of unknown orign.
