This condition has been less frequently seen in dogs, the recognizable
causes having been traumatism (Notz), and leucocythæmia (Zahn,
Forestier, La Forgue, Nocard). Lymphadenoma is another complication
(Nocard, Leblanc, Siedamgrotzky, Bruckmüller). The spleen has been found
to weigh 2 lbs., (Bollinger, Siedamgrotzky). As in other animals the
enlargement of the Paccinian bodies has been a marked feature. In other
cases the splenic lymph glands are enlarged.
The _symptoms_ are obscure as in other animals. Yet the presence of
white cell blood, with a predominance of eosinophile cells, enlargement
of the abdomen, and the detection of a large solid body in the left
hypochondrium which proves tender to the touch may prove more
satisfactory than in other animals. In certain cases it has obstructed
the biliary duct by pressure and entailed hepatic disorder and jaundice.
The _treatment_ would not differ from that of the larger animals.
Siedamgrotzky has also observed splenic hypertrophy in the cat in
connection with leucocythæmia.
