This article describes a case of teratoma, one of the rarest adrenal tumors in children. Initially, despite its large size, it demonstrated all the radiological and histological signs of neuroblastoma. Teratomas are germ cell tumors usually found in the gonads. Adrenal teratomas are extremely rare, accounting for approximately 0.13% of all adrenal tumors. Typically, adrenal teratomas are asymptomatic, as the retroperitoneal space is large enough to accommodate the growth of the tumor without causing symptoms. For the first time in domestic literature, we present a clinical case of adrenal teratoma in a 3-month-old child. The article also presents a detailed description of the diagnostic process and challenges that radiologists and clinicians face when encountering a common tumor in a very rare location for children. This report aimed to help physicians increase awareness of this rare condition and include adrenal teratomas in the potential differential diagnosis of adrenal neoplasms.</p></abstract><trans-abstract xml:lang="ru"><p>Наиболее частое образование надпочечников у детей раннего возраста — это нейробластома, в дифференциальный ряд которой включены такие образования, как нефробластома, кровоизлияние в надпочечник, ангиомиолипома, миелолипома и аденома. В данной статье описан случай одной из самых редких опухолей надпочечников у детей — тератомы, которая на начальных этапах диагностики, несмотря на крупный размер, демонстрировала все рентгенологические и гистологические признаки нейробластомы.</p> <p>Тератомы — это герминогенно-клеточные опухоли, обычно обнаруживаемые в области гонад. Тератомы надпочечников встречаются крайне редко и составляют около 0,13% всех образований надпочечников. Как правило, тератомы надпочечников протекают бессимптомно за счёт того, что забрюшинное пространство достаточно обширно для свободного роста образования.</p> <p>Впервые в отечественной литературе нами представлен клинический случай тератомы надпочечника у ребёнка в возрасте 3 месяцев. В статье также подробно описан ход диагностических исследований и те сложности, с которыми рентгенологи и клиницисты столкнулись, встретив распространённую в детском возрасте опухоль в очень редкой для неё локализации.</p> <p>Данная статья может помочь врачам повысить осведомлённость о таком редком заболевании и включить тератому надпочечников в потенциальный дифференциальный ряд новообразований надпочечников.</p></trans-abstract><trans-abstract xml:lang="zh"><p>神经母细胞瘤是幼儿最常见的肾上腺肿块，其鉴别系列包括肾母细胞瘤、肾上腺出血、血管肌脂肪瘤、骨髓脂肪瘤和腺瘤。本文描述了一例最罕见的儿童肾上腺肿瘤，即畸胎瘤，尽管其体积较大，但在诊断初期却显示出神经母细胞瘤的所有放射学和组织学特征。</p> <p>畸胎瘤是生殖细胞肿瘤，通常出现在性腺区域。肾上腺畸胎瘤极为罕见，约占所有肾上腺肿块的 0.13%。肾上腺畸胎瘤通常没有症状，这是因为腹膜后间隙足够大，肿块可以自由生长。</p> <p>我们首次在俄罗斯文献中介绍了一个 3 个月大儿童肾上腺畸胎瘤的临床病例。文章还详细描述了诊断检查的过程，以及放射科医生和临床医生在罕见部位遇到常见儿童肿瘤时所遇到的困难。</p> <p>文章旨在帮助医生提高对这种罕见疾病的认识，并将肾上腺畸胎瘤纳入肾上腺肿瘤的潜在鉴别系列。</p></trans-abstract><kwd-group xml:lang="en"><kwd>adrenal teratoma</kwd><kwd>case report</kwd><kwd>pediatrics</kwd><kwd>radiology</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>тератома надпочечника</kwd><kwd>клинический случай</kwd><kwd>педиатрия</kwd><kwd>лучевая диагностика</kwd></kwd-group><kwd-group xml:lang="zh"><kwd>肾上腺畸胎瘤</kwd><kwd>临床病例</kwd><kwd>儿科</kwd><kwd>放射诊断</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">WHO Classification of Tumours Editorial Board.
