Malignant Sphenoid Wing Meningioma in Childhood

Hong Kong J Radiol 2012;15:41-6
Paediatric cranial meningiomas are uncommon, constituting 4% of all intracranial tumours in early childhood to adolescent. They frequently show cellular atypia and anaplasia. Paediatric meningiomas arising from the sphenoid wing, although possessing characteristic imaging features, can involve other skull base structures making surgical excision difficult. Prognosis is therefore not as favourable as for lesions at other cerebral convexities. The computed tomographic and histopathological findings, together with the clinical course of a sphenoid wing meningioma that turned malignant, in a 5-year-old boy are presented.

蝶骨翼惡性腦膜瘤小童病例報告
蘇銳新、吳恆堅
小兒顱內腦膜瘤很罕見，通常佔幼兒至青少年各種顱內腫瘤的4%。此症一般出現腫瘤的細胞變異 性及退行分化。起源於蝶骨翼的小兒腦膜瘤雖然具有獨特的影像特徵，但因為可以牽涉其他顱底結 構，很難利用手術進行切除。因此與其他大腦穹隆的腫瘤比較，蝶骨翼腦膜瘤預後不那麼好。本文 報告一名患有蝶骨翼腦膜惡性瘤的5歲男童，包括其CT和組織病理學結果以及臨床表現。
