Image-Guided Radiosurgery for Hypothalamic Hamartomas

Fig. 27.1

Treatment planning of a left sessile HH extending into the interpeduncular cystern near the optic chiasm. This case was treated with frameless image-guided robotic radiosurgery (Cyberknife) delivering 151 beams carrying a total dose of 16 Gy prescribed to the 70 % isodose (Maximum dose: 22.85 Gy)

In conclusion, HH are brain tumors causing a severe epileptic disorder. Conventional surgical resection is an effective treatment for epilepsy and mass effect but carries a high risk of major neurological deficits and complications. SRS provides an efficacious and low-risk non invasive treatment option for small to medium size HH and for post-surgical residuals.
