The clinical aspect, radiological picture and surgical treatment are described. Pathogenesis is discussed on the basis of the literature. Furthermore it is stressed that only the histopathological examination gave the correct diagnosis and permitted the definitive hormonal treatment. To our best knowledge no comparable case has been published in the literature.\nSimilar content being viewed by others\nReferences\nBaker GS, Parsons WR, Welch JS (1966) Endometriosis within the stealth of the sciatic nerve.
