Apart from the anterior mediastinal position and the usual size of the normal thymus, aberrant locations and extreme size variations may occur. This is illustrated by an eight month old boy whose histologically normal thymus presented as a large mass in the right hemithorax. It is the largest normal thymus on record in an infant. Thus, idiopathic thymomegaly should also be considered in the differential diagnosis of peripheral intrathoracic mass lesions.
除了正常胸腺位于前纵隔及其通常的大小外，还可能出现异常位置和极端的大小变化。一个八个月大的男孩就说明了这一点，其组织学上正常的胸腺在右半胸表现为一个大肿块。这是有记录以来婴儿中最大的正常胸腺。因此，在鉴别诊断外周胸内肿块病变时也应考虑特发性胸腺肿大。
