Astroblastoma is thought to arise from astroblast - an intermittent cell between spongioblast and astrocytes and is a rare tumor in the pediatric age group. The histological appearance are characterized by radiating arrangement of spindle-shaped tumor cells forming perivascular pseudorosettes, and being very similar to that seen in ependymomas, makes differentiation difficult. The authors report the case of a 5-year-old girl who had a large frontal tumor, which was thought to be an astroblastoma preoperatively, based on the unique magnetic resonance imaging features these tumors have. The histological findings, in association with the preoperative radiology confirmed the diagnosis of astroblastoma. The authors conclude that the MR imaging of astroblastomas is extremely helpful in differentiating from ependymomas and is used for preparing the histopathology reports in these patients.
