case_images: The CT imaging demonstrated a 2.6 cm mixed-density lesion with heterogeneous enhancement of the upper pole of the right kidney (Figure 1).
case_images: A and B - Magnetic resonance imaging (MRI) of the right kidney showing a 2.7 cm cystic lesion with thickened and enhancing septation (Bosniak III) (A - T1 weighted in-phase sequence, B - T2 weighted fat-suppressed sequence).

case_images: Magnetic resonance imaging (MRI) of the kidney confirmed the 2.7 cm right renal cystic lesion with thickened and enhancing septation (Bosniak III) (Figure 2).
case_images: Gross image of the partial nephrectomy specimen. Cross section reveals a brown multi-loculated cystic mass (1.8x1.5x1.1 cm). The cysts have smooth and glistening walls and no excrescences (scale bar = 1 cm).

case_images: Sectioning revealed a brown multi-loculated cystic mass that measured 1.8x1.5x1.1cm (Figure 3).
case_images: Microscopic images of the lesion. A, B and C - show hematoxylin and eosin (H&E)-stained sections of the lesion, which is composed of cysts of various sizes lined by flattened epithelium and an adjacent normal renal parenchymal tissue separating the cysts; D - shows immunohistochemical (IHC) stains that are positive for PAX8.
