Abscess of the Spleen. 557 



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 hypersemia. Any 

 purulent or septic disease which might coexist would of course 

 serve to indicate a germicide line of treatment. 



ABSCESS OF THE SPI^EEN. 



In Solipeds : in infectious diseases, pysemia, 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, aijtiseptic injections, internal antiseptics. 



Soliped. Ab.scess 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 aud other infectious 

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

 the splenic bloodvessels. The peculiar vascular structure of the 

 spleen is very conducive to ab.scess as ^t 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 diagno.stic ones of splenic 

 disease. Bourges found a .splenic abscess in a cachectic, melanic 

 mule but no definite .splenic symptom 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 kidniey aud containing a floating mass of splenic tissue as 

 large as the closed fist. Rutherford found a neoplajsm connecting 

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

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