Acute inflammation of thekidney may become chronic, or the inflammation may have achronic character from the outset; its results may be suppurationor induration, and consecutive atrophy of the organ. Suppuration in the tissue surrounding the kidney, or perine-j)hritis, is generally the consequence of wounds or injuries, or ofthe extension of inflammation from neighbouring parts. (2) Pyceraic abscesses, if they occur in the kidney, are similar tothose in other organs, and do not call for any special remark. Two conditions which may be confounded with them must,however, be mentioned: —Infarctions, or fibrinous blocks, andcapillary Infarctions or Blocks,—These lesions correspond generally to Fig. Blocks in a granular kidney. The situation of the patch is marked by theirregular outline, which was a deep red. those of the spleen, and, like them, depend upon the arrest ofcirculation in a portion of the gland: the cause being obstruction 676 BLOCKS IN THE KIDNEY. of the arterial brancli. This obstruction is generally occasionedby embolism, a fragment of vegetation from a cardiac valve, orsome coagulum or atheromatous matter from the heart or they are especially common in aortic disease accompaniedby vegetations on the valves, and in acute endocarditis. Some-times no embolus can be traced, and there appears to have beenspontaneous thrombosis in the artery. This is especially likely tooccur in fevers, as in typhoid. The blocks in the kidney have a lessdistinctly conical shape than those in the spleen, the vascular dis-tribution being different, but still this shape is seen in smallerblocks.
