Linear accelerator radiosurgery for central neurocytoma: a case report.
This study presents a case of central neurocytoma successfully treated with linear accelerator (LINAC)stereotactic radiosurgery. Originally, the tumor in the left lateral ventricle was removed by craniotomy, but a small residual mass was detected in follow-up magnetic resonance imagery 6 months after the operation. A further 6 months later, additional radiographic studies revealed that the residual mass had grown. LINAC radiosurgery was then performed, in which 1750 cGy doses were delivered at the 70% level with 3 isocenters (collimator size, 2 cm). The mass was completely absent over the duration of follow-up, including the final MR imagery examination 51 months after radiosurgery. LINAC radiosurgery is suggested to be a good treatment modality for residual or recurrent central neurocytoma.
