Clinicopathological and Radiological Features of Two Cases of Intraventricular Meningioma in Childhood

Abstract: The clinical, radiological and pathological features of two cases of intraventricular meningioma in a 9-year-old boy and a 9-year-old girl are reported. Presenting features included headache, vomiting and somnolence with no localizing neurological signs on physical examination. Neither patient showed evidence of neurofibromatosis. CT scans were helpful in establishing the preoperative diagnoses with uniformly hyperdense, well-circumscribed lesions showing bright enhancement after contrast within the lateral an… Show more

“…In the study by Mallucci et al [1], 5 of 21 pediatric meningiomas were malignant. Byard et al [11] reported two 9-year-old children with intraventricular meningiomas; 1 was fibroblastic/angioblastic and the other fibroblastic. The intraventricular meningioma reported by Curiea et al [12] had atypical features with areas of nectosis and a high nuclear:cytoplasmic ratio, with 15% of cells being positive for Ki 67.…”

“…A localização destes tumores nos ventrículos, mais rara nos adultos, é bem mais frequente nas crianças, sendo que cerca de 15 a 17% dos meningiomas na infância se localizam no sistema ventricular, mais comumente no átrio do ventrículo lateral. A teoria mais aceita sobre a origem destas lesões é a de que elas surgem de células meningoteliais do estroma do plexo coróide [1][2][3][4][5][6][11][12][13] .…”

“…A apresentação clínica varia de acordo com a localização da lesão: tumores da parte anterior do terceiro ventrículo apresentam-se com sintomas de hipertensão intracraniana e hidrocefalia, por vezes intermitente, déficits de memória, distúrbios endócrinos e visuais; as lesões posteriores habitualmente causam hidrocefalia, síndrome de Parinaud e sinais e sintomas cerebelares 4,5,10,11,15 . O diagnóstico é feito pela TC e ou por ressonância nuclear magnética.…”
