Local recurrence after epidermoid cyst surgery is a frequently reported complication, but intraventricular spread after surgery has not yet been described in literature. We present the case of a 61-year-old male patient with steadily progressive headaches after surgical excision of an epidermoid cyst in the right cerebellopontine angle about two months ago. The MRI showed multiple intraventricular FLAIR-hyperintensities with diffusion restriction, suggestive of scattered remnants of the epidermoid cyst. We recommend early postoperative MRI-scans after cranial epidermoid surgery, which should be carefully inspected not only for local remnants but also rare complications like intraventricular spread.
表皮样囊肿手术后局部复发是一种经常报道的并发症，但手术后脑室播散在文献中尚未见描述。我们报告一例61岁男性患者，约两个月前在右小脑桥脑角进行表皮样囊肿手术切除后，出现进行性加重的头痛。MRI显示脑室内多个FLAIR高信号伴弥散受限，提示表皮样囊肿有散在残留。我们建议在颅骨表皮样囊肿手术后早期进行MRI扫描，不仅要仔细检查局部残留，还要检查罕见的并发症如脑室播散。
