We report a rare case of giant cell glioblastoma that was difficult to distinguish from cerebral metastasis. The MRI finding was a ring-enhancing well-circumscribed solitary brain tumor that was very similar to cerebral metastasis. Even when MRI results were considered together with the findings by magnet resonance spectroscopy and perfusion-weighted MRI, it was hard to distinguish between giant cell glioblastoma and cerebral metastasis before surgery. When we find a solitary ring-enhancing intracranial mass with little tendency of invasion, we need to consider the possibility of giant cell GBM as a differential diagnosis.
