Dermoid cysts are benign and congenital ectodermal inclusions. Their occurrence in an intracranial location is quite rare. They constitute 0.1 to 0.7% of all intracranial tumors. Their occurrence in the fourth ventricle and their multicentric feature are extraordinary. A 12-year-old boy was admitted to our clinic with a dermoid cyst with sixth cranial nerve involvement. He had symptoms of increased intracranial pressure. This case is the first dermoid cyst in the literature at this unusual location; a mature tooth structure was found within the cyst, which extended over the cervical subsegments. There was a second dermoid cyst in the thoracic spine (multicentric). Our aim is to present an atypical dermoid cyst along with radiodiagnostic characteristics and macroscopic findings.
皮样囊肿是良性先天性外胚层包涵体。它们发生于颅内的情况相当罕见。它们占所有颅内肿瘤的0.1%至0.7%。它们发生于第四脑室且具有多中心特征的情况非常罕见。一名12岁男孩因患有累及第六对脑神经的皮样囊肿入住我们的诊所。他有颅内压升高的症状。该病例是文献中首例发生于这个不寻常位置的皮样囊肿；在囊肿内发现了成熟的牙齿结构，囊肿延伸至颈段以下。在胸椎处还有第二个皮样囊肿（多中心）。我们的目的是呈现一例非典型皮样囊肿及其放射诊断特征和宏观表现。
