Synchronous Pituitary Adenoma and Tuberculum Sellae Meningioma

同時發生之腦下垂體腫瘤及鞍結節腦膜瘤

摘要


同時發生在鞍部兩種腫瘤是相當罕見的情況,比方說腦下垂體腫瘤合併鞍結節腦膜瘤。術前的鑑別診斷此兩種腫瘤是相當重要的,因為腦下垂體腫瘤可以經鼻蝶竇處理,而鞍結節腦膜瘤通常需要開顱手術切除。我們報告一例五十二歲女性因為視野缺損來就診。磁振照影顯示出有一個鞍部腫瘤(17x7x17毫米),經顯影後顯示不同的訊號強度。經鼻蝶竇處理後,病理結果為腦下垂體腫瘤,術後追蹤一年視力持續惡化,磁振照影顯示鞍結節部分仍有腫瘤,經開顱手術切除後,病理顯示為腦膜瘤。本篇文章將針對此一罕見病例討論,包括磁振照影上的鑑別要點,手術路徑的選擇以及其他相關文獻的回顧。

並列摘要


The presence of two concomitant tumors in the sellar region, for example, pituitary adenoma and tuberculum sellae meningioma, is rare. Preoperative diagnosis and differentiation of these tumors are important because craniotomy is recommended for extirpation of meningioma. We present the case of a 52-year-old woman with visual field impairment. Magnetic resonance (MR) imaging revealed a sellar tumor (17×7×17 mm^3) with two intense signals after enhancement. It was resected and found to be pituitary adenoma and meningioma. The literature on the characteristics of these tumors in MR imaging and the approach options for their surgical resection is reviewed.
