Gewicht und Funktion der Milz bei Polycythämie und Polyglobulie

1. We have studied 50 patients with primary polycythemia by radioisotope scanning (“scintigraphy”). In 96% of these patients the weight of the spleen exceeded 300 g. The mean splenic weight was 720 g. 2. 93 % of 48 cases with secondary polycythemia revealed a mean splenic weight below 300 g, as detected by scintigraphy. The mean splenic weight in this group was 195 g. 3. The scintigraphic determination of splenic size allows polycythemia vera to be distiguished from secondary polycythemia with a high degree of accuracy
