Panel A: CT scan, during a percutaneous aspiration. Note irregular thick cyst wall with nonhomogenous content. Panel B: Gross pathological examination, revealing a thick wall with multiple papillary projections. Panel C: Histologic examination: Scanning magnification showing complex glandular structures embedded in the stroma of the wall (hematoxylin and eosin, original magnification: x 400). Panel D: Higher power demonstrates glands with a cribriform growth pattern and nuclei displaying mild atypia (hematoxylin and eosin, original magnification: x 2000).
