Abstract

The objective of this study is to investigate the Magnetic Resonance Imaging (MRI) and Computerized Tomography (CT) characteristics of multiple meningiomas (MM) which are rarely seen except with Recklinghausen disease. Seven female patients (average age: 49.28 years) with MM who have no family history of Recklinghausen disease are included in this study. All patients were scanned with MRI and one patient was also scanned with CT. Localization, intensity, contrast pattern (dural enhancement), and invasion characteristics were analyzed.Localizations of the tumors were as follows: 4 lesions in convexity, 3 lesions in parasagittal, 1 lesion in olfactorial groove, 1 lesion in tentorium and 1 lesion in sellar region. Multiple tumors were hypo intense in T1 weighted images, hyper intense in T2 weighted images and homogen contrast pattern (dural tail) in all cases. CT characteristics were similar to MRI. Meningiomas are the most common extra axial brain tumors which arise from the durameter and rarely seen in multiples except in Recklinghausen disease. Pathogenesis for multiplicity is largely unknown. Because they are mostly seen in females, as ours role of hormonal factors are speculated.

Özet

Bu çalışmanın amacı, Recklinghausen hastalığı dışında nadir görülen Multipl Meningioma'lı (MM) hastalarınBT (Bilgisayarlı Tomografi) ve MRG (Manyetik Rezonans Görüntüleme) bulgularını incelemektir.Ailesinde Recklinghausen hastalığı öyküsü olmayan, farklı nörolojik şikayetleri olan toplam 7 kadın hasta (yaşortalaması: 49.28) çalışmaya dahil edildi. Bu hastaların 7'sine MRG ve ayrıca 1'sine de BT yapıldı.Lokalizasyon, intensite, kontrastlanma paternleri (dural boyanma) ve çevre dokuya invazyon özellikleriincelendi.MM'ların lokalizasyonlarına göre dağılımında; 4 lezyon konveksite düzeyinde, 3 lezyon parasagital alanda, 1lezyon olfaktor olukda, 1 lezyon tentoryumda ve 1 lezyon da sellar lokalizasyondaydı. MRG'de tüm olgularda T1ağırlıklı sekanslarda hipointens, T2 ağırlıklı sekanslarda hiperintens, paramanyetik kontrast madde sonrasıyoğun ve homojen kontrast tutulumları (4 olguda dural boyanma) gösteren multipl extra aksiyel kitle lezyonlarıizlendi. BT karakteristikleri MRG ile benzer olarak izlendi.Meningiomalar duramaterden köken alan beynin en yaygın extraaksial tümörleri olup Recklinghausen hastalığıdışında multipl olarak çok nadir görülürler. MM patogenezi tam olarak bilinmemekle beraber bizimçalışmamızda olduğu gibi kadınlarda daha sık görülmesi nedeniyle hormonal faktörlerin etkili olabileceği iddiaedilmektedir
