中文摘要 | 雖然胃腸道間質細胞腫瘤是胃腸道最常見的間質腫瘤芴但是它很少發生在食道芴也因此很少是造成縱膈腔腫瘤的原因。在此芴我們提出一個59歲男性以縱膈腔腫瘤表現的食道胃腸道間質細胞腫瘤。當整個腫瘤幾乎都向外生長時芴食道胃腸道間質細胞腫瘤可以長成相當大的縱膈腔腫瘤而不造成病人吞嚥上的症狀緻此時電腦斷層影像上的特徵可能無法與縱膈腔的惡性肉瘤區分。因此芴儘管影像上食道管腔內腫瘤的侵犯很少芴我們也必須將食道胃腸道間質細胞腫瘤列入縱膈腔腫瘤的鑑別診斷中。 |
英文摘要 | Although gastrointestinal stromal tumor (GIST) is the most common mesenchymal neoplasm of the gastrointestinal tract, it rarely arises from the esophagus and is thus very rarely the cause of a mediastinal mass. We report a case of esophageal GIST presenting as a mediastinal mass in a 59-year-old male. If such a tumor has extremely exophytic growth, it may result in a huge mediastinal mass without causing dysphagia. The CT features of a huge well-demarcated mass with heterogeneous enhancement and extensive central necrosis may mimic that of a primary sarcoma of the medi-astinum. Esophageal GIST should be in the differen-tial diagnosis of a mediastinal mass, even if there is little evidence of luminal involvement of the esoph-agus demonstrated on imaging. |
