Menenjiomu taklit eden anormal yerleşimli medulloblastom olgusu
Medulloblastom, pediyatrik çağda en sık görülen primitif nöroektodermal tümör grubundandır. Genellikle vermis kaynaklı ve 4. ventrikül yerleşimlidir. Pontoserebellar açı medulloblastomları oldukça nadir olup çoğunlukla intraaksiyel yerleşimlidir. Bu bölgede sık görülen menenjiom ve schwannom gibi tümörlerle karışabilir. Bu yazıda, 16 yaşında kız çocukta pontoserebellar bölgede ekstraaksiyel yerleşen ve menenjiomu taklit eden medulloblastom olgusu sunulmaktadır.
Unusual localization of medulloblastoma mimicking as meningioma
Medulloblastoma is one of the most common primitive neuroectodermal tumors at pediatric age. It is usually located at fourth ventricle originated from vermis. Pontocerebellar angle medulloblastomas are rare and are mostly localized intraaxially. It can be confused with other tumors such as meningioma and schwannoma which are usually seen at this zone. In this report, a 16-year-old girl having medulloblastoma located at the pontocerebellar angle extraaxially and mimicking as meningioma was presented.
