| 中文摘要 | 縱隔腔血管瘤為一罕見的良性腫瘤,大部分發生在前縱隔,只有少數發生在後縱隔。病患的年齡分佈大部份發生在35歲以前,其中大部份是無症狀、僅在常規身體檢查意外發現;少部份則是以侵患或壓迫到鄰近構造而表現出咳嗽、喘或胸痛。其胸部X光常以典型之縱隔腔腫瘤表現。然而,在快速靜脈注射顯影劑後的胸部電腦斷層掃描常會出現如“積水”般的顯影劑不均勻的分佈在腫瘤內,此時若再出現靜脈石(phlebolith),則幾乎可獲得確定診斷。 我們報告一名62歲女性以反復性胸水,仿似惡性表現的前縱隔腫瘤,但是在打完顯影劑的電腦斷層掃瞄中卻發現該腫瘤與旁邊血管有相同程度顯影而懷疑為血管相關之腫瘤,後經手術切除證實為海綿性血管瘤、藉此一病例描述其臨床表現、影像學特徵、診斷及治療經過,並回顧相關的文獻報告。 |
| 英文摘要 | Mediastinal hemangiomas are rare and benign vascular tumors. They commonly occur in the anterior mediastinum, with a few arising in the posterior mediastinum, and are typically found in young adults aged under 35. They are usually asymptomatic and incidentally detected on a routine chest radiograph. Other presentations, such as cough, chest pain, and dyspnea, are associated with invasion or compression to the adjacent structures. Radiographically, mediastinal hemangiomas usually present as a nonspecific mass. On computed tomography (CT), these tumors demonstrate characteristic "puddles" of contrast medium within the mass, following an intravenous contrast medium administration. The presence of phleboliths is virtually diagnostic. We present the case of an anterior mediastinal mass with recurrent pleural effusion mimicking advanced malignancy. After intravenous contrast medium administration, an enhancement of the mediastinal mass similar to the adjacent vascular structures was found on CT films, and a vascular origin was favored. The fumor was resected and proved to be a mediastinal cavernous hemangioma. We herein report this rare case and review the literature. |
