The clinical, MR imaging, surgical, and histologic findings in two cases of cystic aberrant cervical thymus were reviewed. Aberrant cervical thymic tissue was sharply circumscribed and extended deep to the posterior pharyngeal wall at the level of the piriform sinus in both cases. Both lesions had cyst contents that were of increased signal intensity on T1-weighted images. Solid components displayed MR signal characteristics identical to normal thymus.
回顾了两例囊性异位颈胸腺的临床、磁共振成像、手术及组织学表现。两例中，异位颈胸腺组织边界清晰，均延伸至梨状窦水平的咽后壁深部。两个病变的囊内容物在T1加权图像上信号强度增加。实性成分的磁共振信号特征与正常胸腺相同。
