Thymic cysts are rare lesions, accounting approximately for 1% of all mediastinal masses. We report a case of a 36-year old woman who presented preoperatively with a calcified mass shadow found on a routine chest radiograph X-ray. After further investigation with chest computed tomography (CT), magnetic resonance imaging (MRI), and tests for Myasthenia gravis, a benign mediastinal cyst was diagnosed and the patient underwent median sternotomy and complete surgical excision of the lesion. The histological examination described a multilocular thymic cyst. Thymic cysts are usually associated with thymic epithelial tumors, such as thymomas, or multisystemic morbid conditions such as human immunodeficiency virus (HIV) infection, rheumatologic disease, and Myasthenia gravis. At all follow-up examinations to date, the patient remains healthy.
胸腺囊肿是罕见病变，约占所有纵隔肿块的1%。我们报告一例36岁女性病例，该患者术前在常规胸部X线片上发现钙化肿块阴影。经胸部计算机断层扫描（CT）、磁共振成像（MRI）进一步检查及重症肌无力检测后，诊断为良性纵隔囊肿，患者接受了正中胸骨切开术并完整切除病变。组织学检查显示为多房性胸腺囊肿。胸腺囊肿通常与胸腺上皮肿瘤如胸腺瘤相关，或与多系统疾病如人类免疫缺陷病毒（HIV）感染、风湿性疾病及重症肌无力相关。迄今为止的所有随访检查中，该患者均保持健康。
