摘要

以前没有研究发表过声门下多形腺瘤的磁共振成像（MRI）结果。在此，我们描述了一名 62 岁男性声门下多形性腺瘤患者的病例。内窥镜检查结果显示，声门下后壁长了一个表面光滑的肿瘤。磁共振成像显示，病变在 T1 加权图像上为等密度区，呈均匀强化。该病灶在 T2 加权图像上显示为异质高密度区。弥散加权成像（DWI）显示同一区域的强度略高，表观弥散系数（ADC）正常或仅略高。患者接受了喉镜手术，经口切除了声门下肿瘤，术后诊断为多形性腺瘤。

A Rare Subglottic Pleomorphic Adenoma: Magnetic Resonance Findings.

No previous study has published magnetic resonance imaging (MRI) findings for a subglottic pleomorphic adenoma. Here, we describe the case of a 62-year-old man with a subglottic pleomorphic adenoma. Endoscopic findings revealed a smooth-surfaced tumor arising from the subglottic posterior wall. MRI revealed the lesion as an isointense region on T1-weighted images, which was homogeneously enhanced. This lesion showed a heterogeneously hyperintense region on T2-weighted images. Diffusion-weighted imaging (DWI) showed slightly high intensity in the same area, with a normal or only slightly high apparent diffusion coefficient (ADC). Laryngomicrosurgery was performed for transoral excision of the subglottic tumor, resulting in a postsurgical diagnosis of pleomorphic adenoma.
