[Intraosseous angiography in the elucidation of the pathogenesis of juvenile bone cysts (author's transl)].

The results of intraosseous angiography in juvenile bone cysts suggest that their development is related to an anomaly of early metaphyseal vessels, although it is not established whether one is dealing with a primary ectasia or arteriovenous anastomoses. Juvenile bone cysts therefore belong to the category of congenital diseases. Intraosseous angiography also helps in distinguishing osteolytic processes from fibromas, myxomas, chondromas and osteoblastomas. None of the above-mentioned tumours consists of communicating chambers, such as have been demonstrated in cysts. The treatment consists of complete currettage followed by spongiosa tamponade.
