Abstract
- An astroblastoma is a rare primary glial tumor occurring preferentially in young adults. It is characterized by a perivascular arrangement of the tumor cells forming perivascular pseudorosettes mimicking ependymomas. The histogenesis of astroblastoma is unclear, despite a number of studies to determine its possible cellular origin. We have experienced a case of astroblastoma located at the temporal lobe. It presented as a large, wellcircumscribed, and highly enhanced mass lesion on magnetic resonance images(MRI). The tumor was well demarcated and did not infiltrate the brain, which made complete removal possible. Here, we report and discuss the characteristic histological and radiological features of this case.
