Various diagnostic imagings in nine patients with mediastinal goiters were presented. The clinical manifestations of these patients were various, from totally asymptomatic to severe dyspnea. Six of the nine patients underwent surgical intervention, three were follicular adenomas and three were nodular goiters. A chest radiograph (positive in seven out of nine patients) provided the most valuable initial localization of a goiter mass to the anterior, middle, or posterior compartment. Esophagograms (performed in four patients) showed compression of esophagus by the mediastinal mass. I-131 scintigraphy (performed in seven patients) was capable of detection of functional (in three patients) vs nonfunctional status of thyroid status (in four patients). Angiography (performed in five patients), characterized by anatomic continuity with cervical thyroid gland, calcifications, well-defined border of masses and/or contrast enhancement, offered important roles to direct a diagnosis of intrathoracic goiter. The computed tomography becomes increasingly important because all mediastinal goiters are not radioiodine avid.
介绍了9例纵隔甲状腺肿患者的各种诊断影像学检查结果。这些患者的临床表现各不相同，从完全无症状到严重呼吸困难。9例患者中有6例接受了手术干预，其中3例为滤泡性腺瘤，3例为结节性甲状腺肿。胸部X线片（9例患者中有7例阳性）为甲状腺肿块在前纵隔、中纵隔或后纵隔的初步定位提供了最有价值的信息。食管造影（4例患者进行了此项检查）显示纵隔肿块对食管的压迫。I-131闪烁扫描（7例患者进行了此项检查）能够检测出甲状腺的功能性（3例患者）与非功能性状态（4例患者）。血管造影（5例患者进行了此项检查）的特点是与颈部甲状腺有解剖连续性、钙化、肿块边界清晰和/或造影剂增强，对诊断胸内甲状腺肿起到重要作用。计算机断层扫描变得越来越重要，因为并非所有纵隔甲状腺肿都摄取放射性碘。
