HEREDIA MOY, Klonddy et al. Diagnostic imaging of neurofibromatosis type 2. Report of a case. Gac Med Bol [online]. 2012, vol.35, n.1, pp.28-30. ISSN 1012-2966.

Neurofibromatosis type 2 is a pathology characterized by presenting benign cerebral tumors centrally located. Due to slow growing, they may be inert for many years before symptoms begin. The presence of bilateral or unilateral vestibular schwannomas, is the patron to diagnose NF-2 also see a meningioma, glioma and subcapsular cataracts. We enter the clinical case of a 80 year-old patient, received presenting a clinical diagnosis of 4 months of evolution of progressive start, characterized by oppressive migraine in the front-end area, progressive lost of the hearing, tinnitus, dysmetria, motor deficit, paraparesias, lost of the memory, states of confusion, accompanied by nauseate and vomits in different opportunities. Imaging studies were performed where the TAC reported left frontal tumor, and mixed lesion in right posterior fossa, supratentorial hydrocephalus edema reported transependimario and MRI image compatible with meningioma of the left anterior cranial fossa with significant mass effect and right acoustic neuroma with significant mass effect on the brain stem and fourth ventricle. It was decided to perform resection of both tumors in two surgical sessions; finally the pathology is confirmed compatible with meningioma and acoustic neuroma.
