Intracranial Metastatic Neuroblastoma Treated with Gamma Knife Stereotactic Radiosurgery: Report of Two Novel Cases
Figure 1
Neuroblastoma CNS metastasis treated with Gamma Knife stereotactic radiosurgery. (a) A T1-weighted brain magnetic resonance (MR) image from patient 1 following gadolinium administration demonstrates a 4.0 × 3.3 cm mass in the right parietal lobe. A thin rim of enhancement surrounds the lesion, which contains both cystic and solid components. (b) A T1-weighted brain MR image from patient 1 with gadolinium administration two months following stereotactic radiosurgery (SRS) reveals contraction of the lesion. A reduction in the enhancing components is also demonstrated, though proteinaceous components are still seen within the lesion. (c) and (d) A screenshot of the Leksell GammaPlan 4C treatment planning software is shown for patient 1. The right parietal lesion is targeted in this sequence. A 3D illustration confirms (d) minimal toxicity to surrounding structures.
