Thymic cysts represent 1-3% of all tumors in the anterior mediastinum, but their knowledge is important during the differential diagnosis of a mediastinal mass.
We describe the case of a 52 years old woman, totally asymptomatic, with an incidental diagnosis of a mediastinal mass at thoracic computed tomography evaluation.
Thoracic magnetic resonance showed an heterogeneous mass with approximately 3,6 cm, at the anterior mediastinum. For diagnostic clarification, surgical excision was performed. The histopathological exam revealed an epidermoid thymic cyst.
Surgical excision and histopathological evaluation allow definite diagnosis of this tumor, associated with a good prognosis.
胸腺囊肿占前纵隔所有肿瘤的1% - 3%，但在纵隔肿块的鉴别诊断中了解它们很重要。
我们描述了一名52岁女性的病例，她完全无症状，在胸部计算机断层扫描评估中偶然诊断出纵隔肿块。
胸部磁共振显示在前纵隔有一个约3.6厘米的不均匀肿块。为明确诊断，进行了手术切除。组织病理学检查显示为表皮样胸腺囊肿。
手术切除和组织病理学评估可明确诊断此肿瘤，且预后良好。
