Glioblastoma Misdiagnosed as Brain Abscess after Surgical Evacuation of Spontaneous Basal Ganglia Hemorrhage

A 51-year-old woman presented with sudden severe headache, vomiting, and right hemiparesis at first admission. Computed tomography(CT) scans revealed an hemorrhagic density at left basal ganglia. Preoperative cerebral angiography showed no vascular lesion. Under the diagnosis of hypertensive intracerebral hemorrhage(ICH), total extirpation of hematoma was done. The postoperative neurological condition improved gradually and discharged without any neurological sequelae. Two months later, she revisited with headache, vomiting and progressive right hemiparesis. CT scans at second admission showed an irregular rim enhanced mass with central low density with surrounding edema at the initial bleeding area. Repeated craniotomy was performed and the mass was partially removed. The histopathological diagnosis of the specimen was confirmed as glioblastoma. The authors report a glioblastoma, which occurred at initial ICH site and regarded as a brain abscess with literature review.
