Peripheral retinal neovascularization in a patient with pilocytic astrocytoma.

We described a case of papilledema complicated by peripheral retinal vessels in a 12-year-old boy affected by cerebellar astrocytoma. Opportunity to treat with photocoagulation or intravitreal anti-VEGF (vascular endothelial growth factor) injections was discussed with the parents and no treatment was done. After 5 years from surgery, retinal neovascularization was stable without vitreal hemorrhages or retinal complications, more specifically fibrosis of the neovessels increased and leakage phenomena were reduced at the fluorescein angiography. To our knowledge, this is a unique case of papilledema complicated by peripheral retinal vessels in a patient affected by cerebellar astrocytoma.
