4157 ADVANCED RENAL TUBERCULOSIS
No clinical information is available.
The specimen is of two kidneys from the same patient, one showing more advanced disease than the other. The less affected kidney is 14 cms in length and shows two principal foci of tuberculous disease, one at each pole. Caseous necrosis affects particularly the medulla and has produced marked irregularities of the pyramids. More scattered caseous foci of disease are present in the corresponding areas of the cortex. The midportions of the kidney and the intermediate calyces are not obviously affected. The more severely affected other kidney measures 13 cms in length and shows advanced tuberculous pyonephrosis. The entire pelvis and calyceal is filled with caseous pus and the lining of the cavity is thick, shaggy, pale, friable, caseating material. Only a narrow rind of renal substance remains.
