| 中文摘要 | 我們報告一例罕見的個案是位於前顱窩的出血性上皮樣囊腫。一位六十六歲女性以噁心和嘔吐近一個月為初始症狀,電腦斷層顯示一個混合高低密度腫瘤合併下緣點狀鈣化產生。磁振造影發現腫瘤在T1加重影像主要為高訊號,而在T2加重影像中則是混合高訊號和低訊號並被周圍一圈低訊號環繞。腫瘤內側壁有弧狀顯影。病人接受手術切除腫瘤後,在一年的追蹤內保持良好健康。辨認出特殊的影像表現可以協助恰當的術前鑑別診斷且可預防手術中液態內容物的漏出。 |
| 英文摘要 | We reported a rare case of hemorrhagic epidermoid cyst located in the anterior cranial fossa. A 66-year-old female presented with progressive nausea and vomiting for one month. Computed tomography revealed a mixed high and low density mass in the right lateral frontal basal region, with a few stippled calcifications at its inferior wall. Magnetic resonance imaging showed that the lesion was largely hyperintense on T1 weighted images and was of heterogeneously mixed high and low signal intensity on T2 weighted images. The lesion had a surrounding dark r im and exhibited curvilinear contrast enhancement in its medial margin. The patient underwent total surgical removal of the mass and did well during one year follow-up. Recognition of imaging findings facilitates appropriate preoperative differential diagnosis and is helpful to prevent leakage ofcystic content during surgery. |
