Adenomatoid tumors (ATs) are uncommon, benign tumors of mesothelial origin, most frequently found in the genital tracts of both sexes. Extragenital localization sites, such as adrenal glands, are extremely rare. Since patients with adrenal ATs have no obvious clinical symptoms, imaging examination has become important evidence for diagnosis. Although previous literature noted that the imaging findings of adrenal ATs were nonspecific, no relevant studies have confirmed this. We herein present two novel cases of adrenal ATs, confirmed by immunohistochemistry, and that were initially misdiagnosed as other, more common adrenal tumors based on clinical findings and preoperative imaging. Including our cases, we collected a total of 33 previously reported adrenal ATs and extracted all available imaging information from them, aiming to find some radiological characteristics of this rare tumor. Through the review, we identified some nonspecific imaging features of adrenal ATs; however, the final diagnosis still depends on pathology and immunohistochemistry results.
腺瘤样瘤（ATs）是一种罕见的间皮源性良性肿瘤，最常见于男女两性的生殖道。肾上腺等生殖器外定位部位极为罕见。由于肾上腺ATs患者没有明显的临床症状，影像学检查已成为诊断的重要依据。尽管先前的文献指出肾上腺ATs的影像学表现不具有特异性，但尚无相关研究证实这一点。我们在此报告两例经免疫组织化学确诊的肾上腺ATs新病例，这两例最初根据临床表现和术前影像学被误诊为其他更常见的肾上腺肿瘤。包括我们的病例在内，我们共收集了33例先前报道的肾上腺ATs，并从中提取了所有可用的影像学信息，旨在找出这种罕见肿瘤的一些放射学特征。通过回顾，我们确定了肾上腺ATs的一些非特异性影像学特征；然而，最终诊断仍取决于病理和免疫组织化学结果。
