Abstract

The characteristic MRI of scalp trichilemmal cysts is reported. The feature of an iso-intense area on T1-weighted images is unique to trichilemmal cysts. MRI is helpful in diagnosing the trichilemmal cyst and useful in distinguishing cystic tumors on the median scalp from a cranial malformation, meningo- or encephalocele.

摘要

头皮毛发囊肿的特征性磁共振成像（MRI）表现已被报道。T1加权图像上等信号区域是毛发囊肿独有的特征。MRI有助于诊断毛发囊肿，且有助于鉴别头皮正中的囊性肿瘤与颅骨畸形、脑膜膨出或脑膨出。
