The demonstration of lymphatic channels on wrist arthrography in rheumatoid disease with particular reference to associated lymphoedema.

Delineation of lymphatic vessels is a frequent finding in arthrograms of rheumatoid joints. Arthrography of the rheumatoid wrist when associated with oedema of the upper limb reveals a characteristic pattern consistent with lymphatic obstruction. In our opinion, these findings may be regarded as further evidence in favour of lymphatic obstruction as the cause of peripheral oedema in rheumatoid arthritis. The syndrome appears to be a separate entity from idiopathic oedema of women.
