Radiotherapy is the standard of care for many brain tumors. Unfortunately, it may induce undesirable late complications, such as radionecrosis and oncogenesis. Secondary tumors are most frequently meningiomas, sarcomas (especially fibrosarcoma), and gliomas. [1] A 52-year-old man presented with sudden onset headache, with visual loss, aphasia, and left hemiparesis.
He had a previous history of radiotherapy for an intracranial tumor diagnosed as craniopharyngioma 22 years prior [Figure 1]. External radiotherapy given to the pituitary area was 50 Gy, in 30 fractions, for 47 days. Magnetic resonance imaging (MRI) of the brain showed a well-defined mass in the sellar and suprasellar region, showing a mixed intensity on T2- as well as T1-weighted scans. A computed tomography (CT) scan showed a mass in the sellar and suprasellar region, arising from the clivus, showing a chunky calcification…
