[Radiological study of the chest involvement during angioimmunoblastic lymphadenitis (A.I.L.) Twenty observations...

From 20 observations, the authors worked out the frequency and the radiological picture of chest localizations of angio-immunoblastic lymphadenitis (A.I.L.). There are 2 kinds of pulmonary involvement: --a specific one by interstitial immunoblastic infiltration (20 to 45% of cases) and showing on X ray a reticulomicronodular interstitial syndrome; --a secondary infection (33% of cases) often the cause of death. Pleural involvement is unfrequent (11% to 25% of cases) and its onset late. Mediastinal lymph-node involvement is found in 37 to 50% of cases. It is usually discovered straight away.
