A 61 years old man had generalised seizures 2 years back for the first time in his life. He continued to have repeated seizures despite good drug compliance. A CT Scan head showed a heavily calcified tumour in right frontal lobe with mass effect. This picture is diagnostic of oligodendroglioma. He will be operated in next few days.

CECT and NCCT head showing large right frontal heavily calcified tumour quite typically of oligodendroglioma. Loss of 1p and 19q hetergenity must be looked for. Oligodendrogliomas are slow going tumours. A generous right frontal lobectomy will be done in this case.
