Figures & data
Figure 1. Focal heterogeneous hypodense zone in the anterolateral cortex of the left kidney in arterial phase (A), which became evident in the venous (nephrogram) phase (B). In pyelogram phase images, this hypodense zone became evident: when the margins of this perfusion defect were sharpened by expanding them to 34 mm, the hypodense zone became even more evident (C) (arrows point at the renal vascular damage lesion).
Figure 2. (A)–(C) Following the anticoagulant treatment, a control triphasic CT examination was performed. In this examination, the focal cortical perfusion defect disappeared completely and both the kidneys were reported as completely normal.
