Dynamic contrast-enhanced magnetic resonance images showing the 2 cm lesion in the interpolar region of the right kidney (arrow). In the unenhanced sequence (a) the lesion is isointense to adjacent renal tissue. In the arterial phase (b) the lesion shows peripheral enhancement and in the portal venous phase (c) there is enhancement of the central components in keeping with a solid tumor.

Three years before this presentation she had undergone an elective radical right-sided nephrectomy for a suspected 22 x 26 x 27 mm renal cell carcinoma (RCC) detected on magnetic resonance imaging (MRI) (Fig. 1), which proved to be an RAH after postoperative histologic examination of the specimen.
Contrast-enhanced CT, oblique coronal MPR, showing the atrophied native left kidney (unfilled arrows) with a surrounding subcapsular hematoma (white arrows). There is also blood within the retroperitoneum (red arrows). MPR = multi-planar reconstruction.
