As the inflammatory process extends, the ne-crotic areas become larger and may cause irregular shadowsadjacent to the pelvic outline or appear as irregular areasscattered in various parts of the cortex. Occasionally theoutline of the necrotic area is apparently detached from. Fig. 146.—Renal tuberculosis. the pelvis or connected with it by a narrow isthmus. Againthe areas of necrosis are seen to communicate directly withthe irregular outline of the pelvis. As the inflammatoryprocess advances, the tissue destruction about the pelvismay become that of a large pyonephrosis. The areas ofcortical necrosis may assume irregular forms scatteredthrough the parenchyma, or coalesce to form a large ir- 12 178 PYELOGRAPHY regular sac.

Beyond their apices ir-regular outlines of cortical necrosis are visible. In Fig. 147the necrosis has advanced to such an extent that large, ir- Fig. 147.—Renal tuberculosis. regular areas are visible extending from the dimly outlinedleft pelvis.
