Abstract Adrenal infections are considered clinically important but often go unrecognized, with a significant number of cases only diagnosed post-mortem. The limited evidence regarding imaging findings in the literature emphasizes the need to detect and diagnose these infections early in disease course to improve patient outcomes. A range of microorganisms, including fungi, viruses, parasites, and bacteria, can directly or indirectly affect the morphology and function of the adrenal glands. When evaluating a patient with adrenal infection, several immunological and hormonal factors should be considered, such as the status of the hypothalamic-pituitary-adreno cortical axis and the serum cortisol level. Moreover, certain microorganisms specifically target one of the zones of the adrenal glands or vascular supply, resulting in distinct imaging manifestations. The purpose of this article is to describe the fundamental clinical features and imaging manifestations associated with adrenal infections, enabling radiologists to make informed interpretations and contribute to accurate diagnostic assessments.
