The CT examination of 36 patients with masses in the thymus (three thymus hyperplasias, 33 thymomas) were evaluated retrospectively. Three tumours in atypical positions posed problems in differential diagnosis from bronchial carcinomas and two cases with extensive pleural metastases had to be differentiated from pleural mesotheliomas. There were no certain morphological features on CT which indicated whether the mass was malignant. Eleven patients with thymomas had metastases; in seven of these they were extra-thoracic, with preference for supraclavicular lymph nodes, adrenals and the axial skeleton. Tumour progression and distant metastases were found particularly in malignant thymomas of the epithelial type. Calcification in a thymoma tends to indicate that it is malignant.
对36例胸腺肿物患者（3例胸腺增生，33例胸腺瘤）的CT检查进行回顾性评估。3例位置不典型的肿瘤在与支气管癌的鉴别诊断中存在问题，2例有广泛胸膜转移的病例必须与胸膜间皮瘤相鉴别。CT上没有明确的形态学特征表明肿物是否为恶性。11例胸腺瘤患者发生了转移；其中7例为胸外转移，以锁骨上淋巴结、肾上腺和中轴骨骼为好发部位。肿瘤进展和远处转移尤其见于上皮型恶性胸腺瘤。胸腺瘤内的钙化往往提示其为恶性。
