Case History

A 15-year-old boy was presented to Apollo Speciality Cancer Hospital with complaints of neck pain, tingling sensation and weakness of upper limbs for the past 2 weeks. MRI of the brain and MR angiogram showed an expansile mass in the left cerebellopontine (CP) region. The patient was diagnosed with haemangioblastoma.

Craniotomy was planned as management measure. During the surgery, surgeons found that tumour was highly vascularised, adherent to medulla hence further surgical intervention was not done and patient was referred for CyberKnife®.

The patient was treated with CyberKnife® at a total dosage of 21Gy in three fractions (7 Gy/Fr) to the target. The patient tolerated the treatment well. A significant improvement in the clinical symptoms and a significant decrease in the contrast-enhancing solid mass were observed at third month following the treatment. Currently, the patient is doing well and is on regular follow-up.


Optic nerve sheath meningiomas are benign tumours arising from the optic nerve sheath and are surrounded by numerous critical structures. Fractionated radiation therapy with CyberKnife® provides highly conformal dose distribution in these critically located tumours.
