Chondrosarcoma of the Skull Base-Report of Two Cases

顱底軟骨肉瘤-兩病例報告

摘要


顱底軟骨肉瘤是一種罕見腫瘤,特徵是生長速度緩慢且有可能因為壓迫周邊器官而致命。由於局部解剖構造的限制,常無法以手術完全切除。在軟骨肉瘤、原索瘤、及軟骨性原索瘤之間做鑑別診斷是相當重要的,因為它們有不同的預後。我們報告兩例顱底軟骨肉瘤,起初都以複視來表現,磁振造影術發現有顱底腫瘤。腫瘤切除後,經組織病理學檢查診斷為第一級軟骨肉瘤。正確的診斷和小心的外科治療在顱底軟骨肉瘤的處置上扮演重要的角色。

Chondrosarcoma of the skull base is a rare slow-growing tumor with a potentially lethal outcome due to compression of adjacent tissues. Total surgical excision is often difficult due to local anatomical limitations. The differential diagnosis among chondrosarcoma, chordoma, and chondroid chordoma is important due to their different prognoses. We describe two cases of chondrosarcoma with initial presentations of diplopia. Magnetic resonance imaging (MRI) in each case revealed a skull base tumor. After tumor excision, histopathologic examination showed a grade Ⅰ chondrosarcoma. In conclusion, accurate diagnosis and careful surgical treatment play important roles in the management of chondrosarcoma.
