Ruptured Mediastinal Teratoma Mimicking a Lung Parenchyma Lesion

縱膈腔畸胎瘤破裂造成類似肺臟內病灶之影像:病例報告

摘要


一名二十八歲男性患有反覆性咳血長達十四年。六年前他被告知有縱膈腔腫瘤,但他拒絕開刀。一個月前,他又咳嗽並且大量咳血。胸腔X光片發現右上肺葉靠近肺門的地方有一不規則腫塊。胸腔電腦斷層掃瞄發現右上肺葉及縱膈腔有一個6.8公分不規則腫塊。腫塊的密度不均勻且裡面有脂肪密度的組織。病理組織結果為一破裂的成熟畸胎瘤在前縱膈腔並且影響到右上肺葉。

A 28-year-old man presented with recurrent hemoptysis for 14 years. He had been informed that he had a mediastinal mass 6 years ago, but he had refused surgery. One month before this admission, he suffered from cough with profuse hemoptysis. Chest radiographs showed an irregular mass lesion in the perihilar region of the right upper lung, abutting the mediastinum. Chest CT scan revealed a 6.8-cm tumor mass with irregular tumor margins, involving the upper lobe of the right lung (RUL) and right anterior mediastinum. The mass had inhomogeneous density with fat density within the tumor. Histologic diagnosis was compatible with a ruptured mature teratoma of the anterior mediastinum with involvement of the RUL.
