Abstract:
This report is of a case of gemistocytic astrocytoma investigated by perfusion-weighted magnetic resonance (MR) imaging associated with proton MR spectroscopy. The conventional MR imaging presentation of gemistocytic astrocytoma is similar to that of HGG, metastasis or lymphoma. Nevertheless, a precise diagnosis is crucial as the prognosis and therapy of these diseases are different. Quantitative MR imaging sequences, which provide metabolic and vascular information, could be useful in the prevention of misdiagnosis.
