Bilateral adrenal lymphomas in a 76-year-old man. (A) Axial pre-contrast CT scan and (B) contrast-enhanced axial CT scan images show bilateral adrenal round masses (arrows) with CT attenuation value about 35 HU and slightly enhanced. (C) Axial T2-weighted image after two courses of chemotherapy, the mass decreased significantly, showing low signal intensity at T2-weighted imaging. (D) Photomicrograph (original magnification, ×100; H-E stain) shows tumor cells were large, diffuse, infiltrated, and had significant heteromorphism and the mitotic figures.
