Abstract:
PURPOSE: The purpose of this study is to describe the imaging characteristics of oligodendroglioma in childhood. MATERIALS AND METHODS: Eight CT scans and 12 MR images were retrospectively reviewed in 12 children (mean age, 9.5 years) with pathologically-proven oligodendroglioma. The most frequent symptoms were seizure and headache, with a mean duration before diagnosis of 21 months. Location, MR signal intensity, calcification,intratumoral hemorrhage, cystic change, peritumoral edema and contrast enhancement were retrospectively analyzed. RESULTS: The supratentorial location was most frequent (9/12, 75%) and the majority of tumors were located peripherally or subcortically (7/9, 78%). On MR, most tumors demonstrated low signal intensity on T1WI and high signal intensity on T2WI ; cystic change was frequent (10/12, 83%). Tumor enhancement was seen in 60% of cases (6/10), with various enhancement patterns. Intratumoral hemorrhage was seen in two cases. On CT, the tumors were usually hypodense and calcification was noted in two cases (2/8, 25%). Peritumoral edema and mass effect of the tumor were seen in five (5/12,42%). Hydrocephalus was associated in two cases. CONCLUSION: In childhood, most oligodendrogliomas demonstrate a peripherally located supratentorial mass, with frequent cystic change. Calcification or intratumoral hemorrhage were less frequent than in previously reported adult series.
