case_images: Imaging and pathological examination of the adrenal tumor. (A) Coronal CT with contrast showing left adrenal mass approximately 4.5 x 4.8 cm in size with heterogeneous progressive enhancement. (B) FDG-PET of the left adrenal gland (early SUVmax, 3.56; delayed SUVmax, 3.25). (C) Hematoxylin and eosin stain of adrenal tumor, 40x magnification, well-defined cell borders without capsular invasion. The tumor cells are slightly larger than the surrounding normal adrenal cortical gland cells. (D) Hematoxylin and eosin stain of adrenal tumor, 400x magnification, adenoma cells with abundant foamy cytoplasm. Increase of variation in nuclear size with some high-grade nuclear cell (grades 3-4) was seen, but no mitoses, hyperchromisia, or invasion is noted.
