Case Discussion

MRI detected mass-lesion in left parietal lobe, surgery was performed with radical resection of the tumor and pathological report statement was "ganglioglioma, WHO grade I".

In this case there is an unusual feature of the tumor - areas of restricted diffusion in otherwise benign tumor. There are cases in the literature, describing such phenomenon, attributing it to intermediate cellularity composed of ganglion cells and neoplastic astrocytes. That is why the presence of restricted diffusion itself should not lead to conclusion about malignancy of the tumor, and it is important to acknowledge, that high to intermediate cellularity can lead to restricted diffusion even in low grade benign tumors.
