Congenital masses in the lateral brow are most commonly dermoid cysts and can often be excised surgically without additional investigation. These dermoids may rarely develop intracranial extension due to underlying bony erosions and become less prominent over time - a "disappearing dermoid." However, the authors present an unusual alternative case in which an off-midline frontal encephalocele initially presented as a firm irreducible mass but exhibited changing characteristics over time.
外侧眉部的先天性肿物最常见的是皮样囊肿，通常无需进一步检查即可手术切除。这些皮样囊肿很少会因潜在的骨质侵蚀而向颅内扩展，且随着时间推移会变得不那么明显，即“消失的皮样囊肿”。然而，作者介绍了一个不寻常的病例，一名中线旁额部脑膨出最初表现为一个质地硬且无法回纳的肿物，但随着时间推移其特征发生了变化。
