In this report, we examine the case of a 6-year-old girl with a mixed oligo
dendroglioma demonstrating uncommon neuroradiological images. CT and MR sho
wed an intratemporal mass with multilocular cystic formation and intratumor
al massive calcification, suggestive either of astrocytoma, dysembryoplasti
c neuroepithelial tumor, or ganglioglioma as a presumptive differential dia
gnosis. The tumor was almost completely removed. Post-operative histologica
l examination revealed a mixed oligodendroglioma with a small component of
astrocytoma. The combination of radiotherapy and chemical treatment was sup
plemented. (C) 2001 Elsevier Science Ltd. All rights reserved.
