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.
