The characteristics of patients with adrenal tumors detected during HT screening may differ from those of patients with AIs. This study aimed to compare the characteristics of patients with AIs with those of patients with adrenal tumors detected during HT screening. We retrospectively analyzed patients referred to our division for detailed examination of adrenal tumors between April 2009 and April 2017. When the purposes of imaging tests included HT screening, we defined adrenal tumors as HT associated, otherwise as strictly defined AIs. We reviewed data on age, sex, purpose and modality of imaging, location of tumor, tumor diameter, and hormonal evaluation. We identified 104 patients with HT-associated adrenal tumors and 413 with AIs. Patients with HT-associated adrenal tumors were younger (54.2 years vs. 61.7 years, p
