Abstract：
Multilocular thymic cysts (MTC) are acquired multilocular cysts caused by inflammation. The rarity of such lesions and a lack of recognition make diagnosis and treatment difficult. Herein, we present our experience with a multilocular mediastinal cyst that resulted in the development of thymic cancer with metastasis over a period of 13 years. Computed tomography findings revealed an anterior mediastinal mass that was suspected to be an MTC in a 49-year-old man. The mass shrank gradually over a period of 7 years; however, growth was observed at 10 years after initial detection. At 13 years after detection, thymic carcinoma with multiple lung metastases was diagnosed. Resection was recommended during the follow-up period, but the patient refused treatment. A multilocular wall and location are factors that indicate MTC. However, even if a definitive diagnosis is not made, resection of multilocular anterior mediastinal cysts should be considered as determining the preoperative diagnosis is difficult. Nevertheless, our case suggests that the coexistence of tumors with cysts is possible, and the potential for malignant tumor development exists.
摘要：
多房胸腺囊肿（MTC）是由炎症引起的获得性多房囊肿。这种病变的稀有性和缺乏认识使得诊断和治疗困难。在这里，我们介绍了多房性纵隔囊肿的经验，该囊肿在13年的时间内导致了胸腺癌的发展并转移。计算机断层扫描结果显示，一名49岁男性的前纵隔肿块被怀疑是MTC。质量在7年的时间内逐渐缩小；然而，在最初检测后10年观察到生长。在被发现13年后,诊断为胸腺癌伴多发肺转移。在随访期间建议切除,但病人拒绝治疗.多房壁和位置是指示MTC的因素。然而,即使没有做出明确的诊断，由于确定术前诊断困难，应考虑切除多房前纵隔囊肿。然而，我们的病例表明肿瘤与囊肿共存是可能的，并且存在恶性肿瘤发展的潜力。
