Contrast enhanced axial CT abdomen of a 70-year-old male who presented with clinical features suggestive of acute diverticulitis shows a well-defined, homogenous, low density lesion (asterisk) with mild enhancement in the right upper abdomen. The lesion is located posterior to the IVC (solid white arrow) and superior to the right kidney (double white arrow) suggesting it is originating from the right adrenal gland. As the density of lesion was measured to be 6HU, it most likely represents an adrenal adenoma. Adrenal adenoma is often found incidentally during abdominal imaging and has low density due to presence of intracytoplasmic lipid. On a non-contrast CT an adrenal lesion with attenuation of 10HU necessitating further workup (e.g., contrast enhanced CT or magnetic resonance imaging) for catherization of the lesion
