- Gangliogliomas are rare tumors of the central nervous system(1-1.5% of all primary brain tumors). They can occur anywhere in the central nervous system but are most commonly located in the temporal lobe(75%) and are mainly found in children. A 50-yearold male presented with features of headache,dizziness and altered behaviour. plain CT images shows large intra-axial predominantly cystic lesion with eccentric hyperdense solid component without calcification. Contrast-enhanced magnetic resonance imaging (CEMRI) of the brain showed well defined intense and heterogenously enhancing solid and cystic mass lesion in the left high frontal region with mass effect and midline shift. We report a case of ganglioglioma in 50 years old male in the left frontal lobe (10%),which is rare location which was diagnosed by CT, CEMRI and confirmed at histopathology.
