Benign tumors or tumor-like lesions of the tongue are uncommon lesions that comprise a heterogeneous group of neoplasms. Although there are a variety of benign tumors or tumor-like lesions, the imaging appearance of these diseases is not well defined because of a paucity of scientific literature on this topic. Most benign tongue tumors usually appear as submucosal bulges located in the deep portion of the tongue. Their true features and extent may only be identified on cross-sectional images such as CT and MRI. Thus, CT and MRI play an important role in the diagnosis of these unusual lesions. It is important that radiologists be able to identify the characteristic CT and MR imaging features that can be used to narrow the differential diagnosis with increased diagnostic confidence, suggest specific histologic tumor types. In this pictorial essay, we provide insights into the MRI presentations of benign tongue tumors and tumor-like diseases and their radiologic-pathologic correlation. Benign tumors or tumor-like lesions of the tongue described herein include papilloma, lipoma, hemangioma, venous malformations, schwannoma, neurofibroma, epidermoid cyst, and dermoid cyst.
舌部的良性肿瘤或肿瘤样病变是一组异质性肿瘤，较为少见。尽管存在多种良性肿瘤或肿瘤样病变，但由于关于该主题的科学文献较少，这些疾病的影像学表现尚无明确界定。大多数舌部良性肿瘤通常表现为位于舌深部的黏膜下隆起。其真实特征和范围可能仅在CT和MRI等横断面图像上得以识别。因此，CT和MRI在这些罕见病变的诊断中发挥着重要作用。放射科医生能够识别出特征性的CT和MR成像特征，从而用于缩小鉴别诊断范围、提高诊断信心并提示特定的组织学肿瘤类型，这一点很重要。在这篇图文并茂的文章中，我们深入探讨了舌部良性肿瘤和肿瘤样疾病的MRI表现及其放射学-病理学相关性。本文所述的舌部良性肿瘤或肿瘤样病变包括乳头状瘤、脂肪瘤、血管瘤、静脉畸形、神经鞘瘤、神经纤维瘤、表皮样囊肿和皮样囊肿。
