Objective. Meningiomas are benign primary meningeal tumors and are seen rare in children and adolescents. Clinical Presentation and Intervention. A 15-year-old Turkish boy reported a 1-month history of headache and blurred vision in both eyes. His visual acuity was 0.3 in both eyes with papilledema. Magnetic resonance imaging showed a 77 × 97 × 77 mm intracranial-extra-axial frontal lesion which compresses the chiasm. He was diagnosed with intracranial meningioma and referred to neurosurgery clinic. Conclusion. Ophthalmologists should be aware of the fact that papilledema and low vision can be caused by an intracranial tumor which compresses optic chiasm. 1. Introduction Meningiomas are benign primary meningeal tumors and are seen rare in children and adolescents. hese tumors arise from meninges, covering the brain and spinal cord, and therefore can occur in any number of locations. he diagnosis may be incidental or in response to a workup for ophthalmo- logical or neurological symptoms. Even though they are slow- growing benign tumors, signiicant morbidity may result from compression of the oculomotor nerve, anterior visual pathways, or trigeminal nerve. Tumor expansion may lead to visual loss [1]. he purpose of this case report is to present a case of meningioma in a child associated with compressive optic neuropathy. 2. Case Report A healthy 15-year-old Turkish boy presented with one-month history of headache and visual impairment in both eyes. He visited the neurology department of a hospital one week before, but the results of general physical examina- tion were unremarkable. It was suggested that he visit an ophthalmologist because of his visual disturbance. His best- corrected visual acuity (BCVA) was 0.3 in both eyes. here was papilledema on funduscopic examination (Figure 1). Magnetic resonance imaging (MRI) showed an extra-axial frontal tumoral lesion with intense enhancement (Figure 2). he dimensions of the lesion were measured as 77 × 97 × 77 mm and the lesion was located at superior aspect of the chiasm. MRI scan showed cerebrospinal luid tracking along the optic nerve sheath which is the sign of increased intracranial pressure (Figure 3). Coronal T2-weighted images showed that the mass was also exerting pressure on the chiasm (Figure 4). Dural tail sign on sagittal T1-weighted images airmed the diagnosis of meningioma (Figure 5). He was diagnosed with meningioma which compresses the normal brain tissue above the optic chiasm and referred to neurosurgery clinic. Operation was planned urgently. Ater gross-total resection, the patient progressed well with consid- erable improvement of his visual function. here has been no Hindawi Publishing Corporation Case Reports in Ophthalmological Medicine Volume 2015, Article ID 420964, 3 pages http://dx.doi.org/10.1155/2015/420964
