case_images: Adrenal gland tumor images at the PA diagnosis. Right adrenal tumor images at the time of PA diagnosis were obtained using unenhanced CT (A), enhanced CT (B), out-of-phase MRI (C), and in-phase MRI (D).. PA: Primary aldosteronism.

case_images: A computed tomography (CT) study revealed a 20-mm right adrenal tumor (Figure 1, Panel A). The tumor had 32 HU on non-contrast CT, delayed washout on contrast-enhanced CT, and was lipid-rich on magnetic resonance imaging (MRI) (Figure 1).
case_images: Adrenal gland tumor images before the adrenalectomy. Right adrenal tumor images were obtained just before the adrenalectomy using enhanced CT in the transverse plane (A) and the coronal plane (B).

case_images: However, imaging performed 12 months later revealed that the tumor had grown to 130 mm in size (Figure 2).
case_images: Pathology of the adrenocortical carcinoma. Immunohistochemistry of the tumor cells. Hematoxylin & eosin (H&E) staining (A), steroidogenic factor 1 (SF-1) (B), CYP11B1 (C), and CYP11B2 (D), all at 100x magnification.

case_images: C21 and C17 were expressed in many tumor cells. CYP11B1 and CYP11B2 expression was rarely observed (Figure 3).
