摘要

脈絡球腫瘤是很罕見的，發生於氣管則更少見。在過去文獻中，僅有十五例氣管脈絡球腫瘤的病例報告。我們報告一個氣管脈絡球腫瘤的病例，病患是一位50歲的女性，住院主訴是突發性呼吸急促和咳血。胸部X光發現於右側縱膈腔有一腫瘤造成氣管狹窄；支氣管鏡於氣管分歧處上1.5公分發現一突出於氣管內的腫瘤；造成氣管腔60~70%的狹窄。該腫瘤於電腦斷層攝影中呈現界線清楚的、有顯影的、高密度病灶。在磁振造影中該腫瘤在T1加權影像（T1-weighted image）表現為低訊號；在T2加權影像（T2-weighted image）表現為高訊號；腫瘤訊號均勻，有管狀低訊號的影像。病患接受氣管袖狀段落切除和氣管重建。病理報告為脈絡球腫瘤。電腦斷層攝影及磁振造影有助於氣管脈絡球腫瘤的診斷。病患後來接受外科手術－袖狀段落氣管切除和重建。手術七個月之後，至今狀況仍良好。

Glomus tumors are uncommon neoplasms and the tracheal glomus tumors are extremely rare. During the review of the literature, only 15 cases of tracheal glomus tumor have been reported. Microscopically, the tumor was well-circumscribed and confined within the subepithelial connective tissue and muscle coat, with a pushing margin at the periphery. CT scan manifestations of tracheal glomus tumors were infrequently reported and no MRI finding reported yet. We report the CT and MRI findings of a 50-year-old female with tracheal glomus tumor which are helpful in the diagnosis. This patient received sleeve resection of trachea with reconstruction and has led an uneventful life for 7 months after operation.
