Abscess of the Spleen. 57 7 



The simpler forms recover like cases of simple hypersemia 

 while the severe infecting forms may become the point of de- 

 parture for the formation of multiple abscesses in other organs, 

 and of more or less fatal general infections. 



These conditions can only be discovered post mortem, and any 

 symptoms directing attention to the spleen could only suggest 

 such treatment as would be indicated in hyperaemia. Any puru- 

 lent or septic disease which might coexist would of course serve 

 to indicate a germicide line of treatment. 



• ABSCESS OF THE SPLEEN. 



In Solipeds : in infectious diseases, pyaemia, embolism. Symptoms : of 

 primary disease or ill health. Involving other organs. In cattle : foreign 

 bodies from reticulum, distomata, embolism, microbes. Enlargement : in- 

 volving other organs : seen in left hypochondrium, fever, albuminuria. 

 Treatment . aspiration, antiseptic injections, internal antiseptics. 



Soliped. Abscess of the spleen in this animal is unusual and 

 has only been discovered post mortem. It has been found as the 

 result of the local colonization of pyogenic microbes, in connec- 

 tion with strangles, contagious pneumonia and other infectious 

 diseases and can then often be traced to an infected embolus in 

 the splenic blood vessels. The peculiar vascular structure of the 

 spleen is very conducive to abscess as it is to infarction, as has 

 been already noticed and hence this complication of a pre- 

 existing infection in another part is a natural pathological 

 sequence. Symptoms are rather the general ones of a rigor fol- 

 lowed by hyperthermia than any diagnostic ones of splenic dis- 

 ease. Bouges found a splenic abscess in a cachectic, melanic 

 mule but no definite splenic system was observed even on rectal 

 examination. Nottel found an abscess as large as an infant's 

 head, in the base of the spleen, closely adherent by its sac to the 

 left kidney and containing a floating mass of, splenic tissue as 

 large as the closed fist. Rutherford found a neoplasm connecting 

 the great curvature of the stomach, to the diaphragm, and 

 hollowed out into a series of pus cavities. Fetzner and Cadeac
