Discussion (Related Text)

Oligodendrogliomas are a type of glioma that are believed to originate from the oligodendrocytes of the brain or from a glial precursor cell. These are usually tumours of middle-aged adults. Generally, oligodendrogliomas are well-circumscribed, gelatinous, gray masses. They are usually calcified (70-90% : one of the most frequently calcifying tumours), less often with focal haemorrhage. 20% of these tumours are cystic, and they can often expand a gyrus and remodel the skull. On MRI ,Oligodendrogliomas appear heterogeneous on both T1w1and T2 w1 images because of the presence of intratumoral cysts and calcifications.on T1W1 images ,the tumors appear predominantly hypointense to gray matter ,and on T2w1 images they are most often hyperintense ,with small intratumoral cysts and focal calcification and hemorrhages contributing to the overall heterogeneity.
