title: [A curious beating mass].
abstract: We report an unusual case of a 59-year-old patient who developed a hydatid cyst of the rib. The radioclinical presentation was misleading and positive diagnosis was only obtained at surgery. The rib cage is a highly exceptional localization for hydatid cysts. This case is particularly of interest because of the large number of possible diagnoses for beating masses in this localization and the difficult tumor resection.
