[Radiological features of the rectal manifestations of myelofibrosis(author's transl)].

In addition to the well known changes in bone structure, myelofibrosis can result in extramedullary tumour formation; in the gastr-intestinal tract, proliferation of reticulum can lead to fibrotic changes. This results in appearances similar to linitis plastica or Crohn's disease. In the discussion, the authors refer to tumours in other organs which have been described in the literature and which can be demonstrated radiologically.
