Abstract

A 33-year-old male was admitted with complaints of cough, dysphagia, and swelling of face and upper extremities. Chest X-ray and CT scan revealed a large mediastinal mass and infiltrates in the right upper lobe. Percutaneous biopsy proved the mediastinal tumor as thymoma with cellular atypia. After irradiation, the tumor was surgically removed. Caseous epitheloid granulomas were found in the dissected mediastinal lymph nodes. AFB (Acid fast bacillus) stain of the patient's gastric fluid was positive for Mycobacterium. The coexistence of these two diseases was incidental, however, this case suggested that clinicians should perform careful evaluation of lung parenchyma as well as mediastinum on chest X-ray to identify occult diseases including pulmonary tuberculosis in patients with mediastinal mass lesion.

摘要

一名33岁男性因咳嗽、吞咽困难以及面部和上肢肿胀入院。胸部X线和CT扫描显示纵隔有一个大肿块，右上叶有浸润影。经皮活检证实纵隔肿瘤为伴有细胞异型性的胸腺瘤。放疗后，肿瘤被手术切除。在切除的纵隔淋巴结中发现了干酪样上皮样肉芽肿。患者胃液的抗酸杆菌（AFB）染色显示结核分枝杆菌阳性。这两种疾病的并存是偶然的，然而，该病例提示临床医生在胸部X线检查时应仔细评估肺实质以及纵隔，以识别纵隔肿块病变患者中包括肺结核在内的隐匿性疾病。
