There is a vast spectrum of pathology that afflicts the floor of mouth in children. These span inflammatory conditions, vascular malformations, developmental anomalies, benign tumors and malignancies. While this area is readily evaluated on clinical exam, imaging is often performed to better characterize the disorder prior to management. The imaging modalities most frequently utilized are US, CT and MR. The purpose of this article is to describe the primary conditions that occur in this location in children so that radiologists may provide an appropriate differential diagnosis. These include ranula, venolymphatic malformation, dermoid, teratoma, foregut duplication cyst, hairy polyp, thyroglossal duct cyst and rhabdomyosarcoma. For each pathological condition, there will be a focus on describing its imaging manifestation. Floor of mouth anatomy, imaging approach during both prenatal and postnatal life and etiologies will be discussed. Surgical considerations and operative photographs will also be presented.
儿童的口底部位会发生各种各样的疾病。这些疾病包括炎症、血管畸形、发育异常、良性肿瘤和恶性肿瘤。虽然临床检查可以很好地评估这个区域，但为了在治疗前更好地对疾病进行定性，通常还会进行影像学检查。最常使用的影像学方式包括超声、CT 和 MRI。本文的目的是描述儿童口底部位发生的主要疾病，以便放射科医生能够提供适当的鉴别诊断。这些疾病包括舌下囊肿、静脉-淋巴管畸形、皮样囊肿、畸胎瘤、前肠重复囊肿、毛状息肉、甲状舌管囊肿和横纹肌肉瘤。对于每种病理情况，本文将重点描述其影像学表现。还将讨论口底解剖结构、产前和产后的影像学检查方法以及病因。本文还将介绍手术注意事项和手术照片。
