A 38-year-old woman with clear cell RCC of the right kidney mimicking segmental enhancement inversion (see Fig. 2). a The nephrographic phase of the axial CE-CT demonstrates avid contrast enhancement and an area of central low attenuation (arrow). b The enhancing area in the nephrographic phase (a) washes out to low attenuation in the delayed phase. The low attenuation area in the nephrographic phase shows relatively high attenuation (arrow)
