Sacrococcygeal teratomas are the most common solid tumor in newborn infants. The diagnosis is not difficult in many cases; however, there should be additional information on imaging studies in order to manage those infants properly. Details include histology, morphologic classification, complications such as rupture, bleeding, and mass effects on the adjacent structures. Although imaging features cannot accurately predict the histologic subtypes of the tumors, thorough evaluation of the imaging features can help distinguish malignant tumors from benign tumors. In this article, pathogenesis, histological characteristics, clinical considerations, and morphologic characteristics will be discussed.
骶尾部畸胎瘤是新生儿最常见的实体瘤。在许多情况下诊断并不困难；然而，为了妥善处理这些婴儿，影像学研究应提供更多信息。细节包括组织学、形态学分类、诸如破裂、出血等并发症以及对相邻结构的肿块效应。尽管影像学特征不能准确预测肿瘤的组织学亚型，但对影像学特征进行全面评估有助于区分恶性肿瘤和良性肿瘤。本文将讨论其发病机制、组织学特征、临床考量及形态学特征。
