ANEURYSM OF ARCUATE ARTERY, 22343

22343              ANEURYSM OF ARCUATE ARTERY

 

No clinical information is available.  The patient was a man aged 60.

 

The specimen is of a kidney measuring 12 cms in length. The surface is irregular and shows some old pyelonephritic scars and some nephrosclerotic granularity. On the cut surface there is a large saccular aneurysm measuring 2 x 4 cms on the hilar aspect at the lower pole. The aneurysm is filled with laminated thrombus. The ureter is normal. Histology shows focal pyelonephric changes in the kidney and intense chronic inflammatory infiltration of the wall of the aneurysm. There are some patches of granulation tissue with mononuclear and capillaries in the fibrous aneurysmal wall but this is considered to be a reaction to the process of dilatation rather than polyarteritis or mycotic aneurysm, for neither of which was there any other evidence.
