BACKGROUND
Dermoid cysts are benign ectodermal growths that commonly form at cranial sutures. Although benign, resection is often recommended to prevent intracranial extension as the cyst grows. The prognosis after resection is very good, provided a complete resection is possible.
OBSERVATIONS
The authors present the case of a 10-month-old male patient with an occipital scalp dermoid cyst with intracranial extension who underwent subtotal resection and later presented with cerebellar extension.
LESSONS
Scalp dermoid cysts with intradiploic extension have a significant risk of intracranial extension. Thus, care must be taken to achieve total resection in the first attempt or provide close follow-up before intracranial extension develops. https://thejns.org/doi/10.3171/CASE2548.
背景
皮样囊肿是常见于颅缝处的良性外胚层生长物。尽管是良性的，但随着囊肿生长，通常建议进行切除以防止颅内扩展。如果能够完全切除，切除后的预后非常好。
观察结果
作者报告了一例10个月大男性患者，患有枕部头皮皮样囊肿并伴有颅内扩展，该患者接受了次全切除，后来又出现了小脑扩展。
经验教训
具有板障内扩展的头皮皮样囊肿有显著的颅内扩展风险。因此，必须在首次尝试时进行完全切除，或者在颅内扩展发生前进行密切随访。https://thejns.org/doi/10.3171/CASE2548
