CT angiogram images, demonstrating bilateral renal artery lobar branch dissections (white arrows) on the right (A and B) and left (C), as well as associated parenchymal infarcts (white arrowheads). Digital subtraction angiogram of the right renal artery (D) demonstrating lobar and segmental branch dissections (white arrows), segmental branch occlusion (black arrow) and infarcted parenchyma (white arrowheads). Excreted contrast is also noted in the renal pelvis (P).

A CT angiogram of the renal arteries was performed, showing a new left lower pole renal infarct and a left renal artery segmental branch dissection (Figure 1).
Renal CT angiogram 15 months after the initial insult. Demonstrates chronic infarcts and atrophy of the lower renal poles (arrowheads) of the right (A) and left (B) kidneys.

A Renal CTA at this time demonstrated chronic bilateral infarcts and persistent, but improved perivascular inflammatory changes of the celiac and renal arteries without recurrent or new dissection (Figure 2).
