[Spinal sub-dural hydatidosis. A report on one case (author's transl)].

A case of spinal sub-dural hydatidosis was observed in an adult patient in whom no parasites were detected any where in the CNS, or even in the spine. Two large and several small cysts were excised from the L2 region of the spine. A discussion is centred on a comparative study of cases published in the literature, which now number twelve if this present observation is included.
