[A contribution for the radiological study in the open hydatic cysts of the kidney (author's transl)].

An observation of an open hydatic cyst of the kidney led the author to discuss, on the basis of pathologic correlation, about the possibilities and limits in the radiological study of renal hydatidosis, in general, and of open forms, in particular. Since pielography is still the only research in a position to show very suggesting radiological findings for the diagnosis of this form of hydatidosis, whose personal case is almost a paradigmatic example, the author emphasizes the need to apply it in these occurrences.
