Ectopic thymoma is a rare tumor that arises from the abnormal migration of thymus tissue. They are extremely rare and have a broad spectrum of clinical symptoms. Therefore, preoperative diagnosis is complex and can be easily misdiagnosed. Complete resection is the treatment of choice to avoid recurrence, radiotherapy and enhanced survival. Regretfully, many patients arrive at a late stage, limiting our therapeutic options; therefore, pre-operative diagnosis is vital. We present the case of an otherwise healthy 32-year-old woman; after a chest X-ray was done for a routine medical evaluation, a mass was discovered in her mediastinum. After surgery, a B2 thymoma attached to the pericardium was discovered and successfully treated.
异位胸腺瘤是一种罕见的肿瘤，由胸腺组织异常迁移引起。它们极为罕见，临床症状广泛。因此，术前诊断复杂，容易误诊。完整切除是避免复发、放疗和提高生存率的首选治疗方法。遗憾的是，许多患者就诊时已处于晚期，限制了我们的治疗选择；因此，术前诊断至关重要。我们报告一例32岁健康女性的病例；在进行常规医学评估的胸部X光检查后，发现她的纵隔有一个肿块。手术后，发现一个附着于心包的B2型胸腺瘤并成功治疗。
