Multiple foci of nephritis of the upper pole of the right kidney. Axial CT slice through the abdomen from CT scans without injection of intravenous contrast (photo 1), CT Scout view (photo 2), and with injection of intravenous contrast (photos 3 and 4). B, back; Bo, bottom; F, front; L, left; R, right; T, top. CT scan found multiple triangular hypodensities (indicated by the red arrows) of the right superior polar renal cortex in favor of foci of nephritis. Absence of contrast of the right pyelic walls. There was no dilatation of the right and left pyelocaliceal cavities. There was no parenchymal abnormality of the left renal pelvis. The bladder was in low replenishment. There was no evidence of lithiasis in the urinary excretory tract. There was no abnormality in the hepatic, splenic, pancreatic, or adrenal compartments. No intraperitoneal or retroperitoneal effusion was observed. There was a good permeability of the vascular axes. Conclusion: multiple foci of nephritis of the upper pole of the right kidney; no dilatation of the pyelocaliceal cavities or obstruction of the urinary excretory tract
