FONS MARTINEZ, M.R.; ESPANA GREGORI, E.; AVINO MARTINEZ, J.A.  e  HERNANDEZ PARDINES, F.. An optic nerve tumor in Von Hippel-Lindau disease, masquerading as a retinal hemangioma. Arch Soc Esp Oftalmol [online]. 2006, vol.81, n.5, pp.293-296. ISSN 0365-6691.

Clinical case: A 35-year-old man with a family history of von Hippel-Lindau disease was diagnosed to have two retinal hemangiomas in the right eye and another in the left eye. The hemangiomas were treated with cryotherapy and laser photocoagulation respectively. Despite apparent good resolution of the retinal lesions, progressive visual loss was observed. An MRI was then performed and showed bilateral tumoral lesions of the optic nerve compatible with a glioma, meningioma or hemangioblastoma. Currently the visual acuity in his right eye is hand movement, and is 0.6 in the left eye. Discussion: The presence of the retinal hemangiomas delayed the diagnosis of an optic nerve tumor in this patient.
