Abstract

Pleural hydatidosis is usually secondary to a rupture of a hydatid cyst of the lung or liver into pleura. The primitive, isolated and unruptured pleural form is rare. We report a case of a woman, living in an endemic area for hydatidosis, diagnosed with an isolated, unruptured, scissural pleural primitive hydatid cyst which looks like mass on lung imaging. This case emphasizes that, isolated, unruptured, scissural pleural primitive hydatid cyst can be mistaken for a lung mass and that surgery remains both a useful diagnostic and therapeutic approach to its management.
