The article describes a patient with a right paratracheal bronchogenic cyst in whom the preoperative diagnosis was unclear. The fluid component of the cyst was not readily apparent by CT or T1-weighted MR images. Very intense signal on T2-weighted MR images suggested a cystic lesion. Inhomogeneities evident on MR but not CT images provided further soft tissue characterization. These soft tissue elements correlated with a macroscopic ring of hyaline cartilage in the resected specimen. The usefulness of MRI for the differential diagnosis of mediastinal tumors is discussed.
本文描述了一名患有右气管旁支气管囊肿的患者，其术前诊断不明确。囊肿的液体成分在CT或T1加权磁共振图像上不易显现。T2加权磁共振图像上的极高信号提示为囊性病变。磁共振图像上可见但CT图像上未见的不均匀性提供了进一步的软组织特征。这些软组织成分与切除标本中的透明软骨宏观环相关。本文讨论了MRI在纵隔肿瘤鉴别诊断中的作用。
