Epidermoid cysts are rare benign intracranial tumors of congenital origin. They are slow-growing and are seen to insinuate between brain structures. These are commonly located in cerebello-pontine angle and parasellar regions. The symptoms produced are primarily due to mass effect. Hearing loss, facial nerve palsy, and trigeminal neuralgia are reported when cranial nerves are involved; motor palsy of trigeminal nerve is uncommon. Here, we present an interesting case of an extensive multicompartmental epidermoid cyst causing atrophy of trigeminal nerve with radiologic evidence of chronic motor trigeminal nerve palsy characterized by atrophy of masticator space muscles and parotid gland.
表皮样囊肿是一种罕见的起源于先天的良性颅内肿瘤。它们生长缓慢，被认为是在脑结构之间潜行生长的。这些肿瘤通常位于桥小脑角和鞍旁区域。产生的症状主要是由于肿块效应引起的。当颅神经受累时，会出现听力损失、面神经瘫痪和三叉神经痛；三叉神经运动性瘫痪并不常见。在这里，我们介绍了一个有趣的病例，一个广泛的多腔表皮样囊肿导致三叉神经萎缩，影像学证据显示慢性运动性三叉神经瘫痪，特征为咀嚼肌和腮腺萎缩。
