[Hepatosplenic sarcoidosis. Contribution of parenchymatous hepatosplenography by selective arteriography].

In this study of hepato-splenic sarcoidosis the authors, in addition to confirming the principle and commonly recognised features of the disease, stress the value of cataloguing the morphological changes, in the liver and spleen by selective arteriography of the coeliac trunk; increase in the frequency of recognition of hepatosplenomegaly; granular appearance of the parenchyma of both organs, which appear to be studded with a multitude of small lacunae, thus eliminating the homogeneous and uniformly opaque image seen normally. Seen in 28.5 p.cent of cases, this heterogeneous appearance is not strictly pathognomic of sarcoidosis. It is mainly due to the lacunar appearance which probably represents sarcoid follicles. It may resolve under cortisone therapy.
