The growing demand for imaging tests and the progressive aging of the population have led to a progressive increase in the detection of indeterminate adrenal lesions. Once an adrenal incidentaloma is detected, clinical and hormone tests together with a battery of imaging techniques (CT, MRI, PET/CT…) make it possible to determine the cause in most cases. In this article, we discuss the advantages and limitations of each technique. We show the imaging characteristics of the most common adrenal lesions and propose a diagnostic algorithm to enable their diagnosis.

Background: A right adrenal gland may present in the form of adreno-hepatic fusion (AHF), in which the adrenal cells are interspersed among the hepatocytes without septation. This rare, naturally-occurring phenomenon may be associated with preoperative misdiagnosis. We present two cases of adrenal tumor in patients with AHF that were misdiagnosed, despite thorough preoperative work-ups.

Background: Superselective adrenal artery embolization (SAAE) represents a novel therapeutic strategy for managing primary aldosteronism (PA). Currently, the evaluation of its efficacy is primarily restricted to clinical indicators, with a notable deficiency in imaging evaluation methodologies. In recent years, several studies have investigated the application of Ga-Pentixafor PET/CT for the classification of PA.

Incidental adrenal masses are frequently detected due to the extensive use of cross-sectional imaging, with about 3% to 7% of adults estimated to have them. Paragangliomas and pheochromocytomas (PPGL), rare tumors originating from paraganglia tissues, including the adrenal medulla, continue to be imaging mimics, necessitating a multimodal approach for accurate diagnosis. We report a case of 72-years male presenting with intermittent pain abdomen for the past 1 year.

Unlabelled: Bladder paragangliomas are rare extra-adrenal urological tumors that account for around 0.05% of bladder cancers. Their diagnosis is often delayed because of the rarity of these tumors.

Objectives: To evaluate the performance of a 3D V-Net-based segmentation model of adrenal lesions in characterizing adrenal glands as normal or abnormal.
Methods: A total of 1086 CT image series with focal adrenal lesions were retrospectively collected, annotated, and used for the training of the adrenal lesion segmentation model. The dice similarity coefficient (DSC) of the test set was used to evaluate the segmentation performance.
