Abstract:
A 63-year-old woman was admitted because of right hemiparesis. Both computed tomography scan and magnetic resonance imaging revealed a mass lesion in the left parieto-occipital lobe. Twenty years previously, meningioma of the left parieto-occipital region was removed at another hospital, and a dural plasty was performed using a silastic dural substitute. The patient was operated on under the diagnosis of recurrent meningioma. However, most of the mass lesion was composed of an old hematoma, which seemed to be a complication of the silastic dural substitute.
