Primary optic nerve sheath meningioma.
Fifty patients with optic nerve sheath meningiomas have been reviewed with a follow-up of up to 15 years. The median age at onset of their symptoms was 40.0 years. The majority were middle aged females with a slowly progressive lesion. More aggressive lesions were encountered in a younger, predominantly male group of patients with frequent intracranial involvement. Our experience indicates that...

A 62-year-old woman diagnosed with a pancreatic neuroendocrine tumor (NET) underwent surgery in 2004 and was reoperated in 2009 for recurrence in the greater curvature of the stomach. Theposterior clinical and radiological controlswerenegative until 2011. InMarch 2011 a somatostatin receptor scintigraphy with 99mTcEDDA/HYNIC-TOC was performed to rule out new recurrence which was suspected due t...
متن کاملPediatric primary optic nerve sheath meningioma
Primary optic nerve sheath meningioma (PONSM) is extremely rare among children. We report two cases of pediatric PONSM. The first case was a 12-year-old boy who presented with gradual visual loss of his right eye and was found to be associated with neurofibromatosis type 2. The second case was a 10-year-old boy who presented with gradual proptosis of his left eye with normal visual acuity. Seve...
متن کاملDiagnosis and treatment of orbital optic nerve sheath meningioma.
BACKGROUND Primary and secondary optic nerve sheath meningiomas (ONSMs) are neoplasms that account for a large proportion of optic nerve and orbital tumors. The diagnosis is not always straightforward and is based on the appropriate clinical findings and neuroimaging. Biopsy or surgical intervention may occasionally be necessary but is associated with significant morbidity. METHODS Issues rel...
متن کاملOptic nerve sheath meningioma: current diagnosis and treatment.
Optic nerve sheath meningiomas (ONSMs) are rare tumors of the anterior visual pathway and constitute approximately 2% of all orbital tumors and 1-2% of all meningiomas. Untreated ONSMs almost always lead to progressive visual decline, color blindness, and finally complete loss of vision. Although resection is warranted in cases of widespread ONSM, surgery can lead to significant morbidity. Rece...
