A thymolipoma is a slow-growing, anterior mediastinal tumor, rare in childhood. The authors present a report of a 4-year-old girl with persistent right thoracic hypotransparency on the chest radiograph. Computed tomography and magnetic resonance imaging revealed an anterior, well-limited, mediastinal mass of heterogeneous density, with lipomatous and soft tissue density areas. The tumor was totally excised and the histopathologic findings revealed a thymolipoma. A year and a half after surgery, the child remains well. This report enhances the relevance of differential diagnosis in the presence of persistent radiologic thoracic hypotransparency.
胸腺瘤是一种生长缓慢的前纵隔肿瘤，在儿童中罕见。作者报告了一名4岁女孩，胸部X线片显示右胸持续透亮度减低。计算机断层扫描和磁共振成像显示前纵隔有一个边界清晰的、密度不均匀的肿块，有脂肪组织和软组织密度区域。肿瘤被完全切除，组织病理学检查结果显示为胸腺瘤。术后一年半，患儿情况良好。本报告强调了在存在持续性胸部透亮度减低的影像学表现时进行鉴别诊断的重要性。
