AB027. Distinguishing oligodendroglioma from astrocytoma: a radiological case report

Differentiating between oligodendroglioma and astrocytoma poses a significant challenge due to their overlapping clinical and radiological features, yet understanding their key differences is crucial for accurate diagnosis. On MRI, calcification strongly favors oligodendrogliomas, while T2/fluid-attenuated inversion recovery (FLAIR) mismatch sign favors astrocytoma. Only 50% of oligodendrogliomas appear to be contrast-enhanced. While oligodendrogliomas and astrocytomas share some similarities, careful consideration is essential for accurate differentiation, even though histopathological and molecular findings are the final determinants of diagnosis.
