Abstract

A 72-year-old man presented with a space-occupying lesion at the site of the prior craniotomy one year after removal of a convexity meningioma with an extracranial extension. The lesion had grown outside the duraplasty with extracranial extension through the degenerative cranioplasty, and was removed. The histological diagnosis was granulation. The original dura-cranioplasty had been performed using Goretex dura substitute, hydroxyapatite cement, and fibrin glue-bonded autologous bone dust. This rare case of foreign body granuloma occurring after craniotomy with dura-cranioplasty indicates that detailed preoperative evaluation of tissue destruction based on neuroimaging is essential for construction of a suitable cranioplasty.
