Early appearance of high grade glioma on magnetic resonance imaging.
The early appearance of high grade glioma on magnetic resonance (MR) imaging was retrospectively reviewed in the clinical records and MR images of 52 patients with intracerebral glioma treated in Osaka General Medical Center between 1997 and 2006. Three patients had no abnormal findings, and four patients had only hyperintense areas on T(2)-weighted imaging at initial MR examination. Five of the seven patients presented with generalized seizures. Six of the seven patients developed tumor progression within only 5 months. All patients underwent surgical tumor resection and the histological diagnoses were all high grade gliomas, glioblastomas in five, gliosarcoma in one, and anaplastic astrocytoma in one. Surveillance MR imaging should be performed at short intervals in adult patients presenting with seizures but with no or minimal abnormalities on initial MR imaging to identify progression of high grade glioma at the earliest opportunity.
