Pre-operative computed tomography (CT) of the anterior mediastinum was performed in eight patients undergoing surgery for cardiac conditions. At operation the anterior mediastinum was generously biopsied. Histology of the material allowed evaluation of the proportion of normal residual thymic tissue. Wide variation in CT appearances and in the degree of thymic involution was found, but there was good correlation between CT findings and thymic histology. This normal variation is of importance when considering the CT diagnosis of anterior mediastinal soft tissue density tumours.
对8例接受心脏疾病手术的患者进行了术前前纵隔计算机断层扫描（CT）检查。手术中对前纵隔进行了广泛活检。对取材组织进行组织学检查，以评估正常残留胸腺组织的比例。结果发现CT表现和胸腺退化程度存在很大差异，但CT表现与胸腺组织学之间具有良好的相关性。在考虑前纵隔软组织密度肿瘤的CT诊断时，这种正常变异具有重要意义。
