舌下囊肿

Those with heterogeneous enhancement were often of acquired etiology, such as ranula, lymphoma, neurilemmoma, parotid adenoma, metastatic nodes and tubercubus adenitis, etc.

至於那些有异质性加强的病变，通常属於后天性疾病，例如：舌下囊肿、淋巴瘤、神经鞘瘤、腮腺瘤、转移性淋巴结、结核性淋巴腺炎等。

Since the lesion presented above is localized both intra- and extralaryngeal, herniates through the thyrohyoid membrane into the submandibular space, is fluid-filled and communicates with the laryngeal ventricle, the cyst is most likely a mixed laryngocele. Differential diagnosis consists of ventricular appendix, thyroglossal duct cyst, submucosal cyst, abscess or pyolaryngocele.

如果一个病变表现为局限性的喉内或喉外病变，通过甲状舌骨膜疝入到下颌下间隙，其内充满了液体，通过喉室相交通，最有可能的就是混合性喉气囊肿，鉴别诊断包括ventricular appendix，甲状舌管囊肿、粘膜下囊肿、脓肿或感染性喉气囊肿
