Magnetic resonance imaging (MRI) showed a large homogenous cystic mass measuring 8.5 x 9.5 cm with well-defined contours, being hypointense on T1-weighted images and hyperintense on T2-weighted images on the upper pole of the left kidney without a distinct plan between adrenal gland (Figure 1).
Multicystic architecture with dilated spaces lined by flattened lining cells (HE x20).

The cystic spaces occasionally contained proteinaceous material, lacking red blood cell content, and the cyst wall contained adrenal cortex (Figure 2).
The flattened cells lining the cyst stained positive for D2-40 (x400).

On immunohistochemical stains, D2-40 cytoplasmic staining was positive (Figure 3), whereas calretinin and CD34 were negative, thus, confirming their lymphatic nature.
