Vanishing brain tumor is defined as spontaneously disappearing or decreasing of the initial brain mass volume to ≤ 70% before establishing the definitive diagnosis. The condition is rare and can be attributed to different factors. The exact mechanism is under debate, but the increasing rate and accuracy of neuroimaging studies and occurrence of similar scenario in other pathologies rather than brain tumors can be of particular importance in finding vanishing brain lesions.
We present two unusual cases of congenital brain masses which underwent spontaneous shrinkage within the first months of life.
The condition is scarcely observed in congenital brain masses. As congenital brain lesions are distinct entities with peculiar characteristics, this rare phenomenon may reflect different aspects in this age group.
消失性脑瘤是指在明确诊断前，初始脑质量体积自发消失或减少至≤70%。这种情况很少见，可能归因于不同的因素。确切的机制仍存在争议，但神经影像学研究的发生率和准确性不断提高，以及在其他病变而不是脑瘤中出现类似情况，对于发现消失性脑病变具有特别重要的意义。
我们介绍了两个不寻常的先天性脑肿块病例，它们在生命的头几个月内自发缩小。
这种情况在先天性脑肿块中很少见。由于先天性脑病变是具有特殊特征的独特实体，这种罕见现象可能反映了该年龄组的不同方面。
