Abstract

Endobronchial lipoma is a rare benign tumor in the bronchial tree. We report a case of endobronchial lipoma in a 73-year-old man with hemoptysis. Chest radiograph revealed atelectasis of the right upper lung. Bronchoscopy revealed a well-defined endobronchial lesion in the right upper lobe bronchus with near total occlusion, but a biopsy was not performed. An endobronchial tumor was identified on CT scan with demonstration of fat within the tumor. Endobronchial lipoma was diagnosed and a sleeve lobectomy of the right upper lobe bronchus was performed. The pathological diagnosis was submucosal lipoma. The patient's symptoms improved during follow-up of more than 1 year. CT scan can be used to diagnose endobronchial lipoma and can help in the development of a management plan.

摘要

支气管内脂肪瘤是支气管树中一种罕见的良性肿瘤。我们报告一例73岁咯血男性的支气管内脂肪瘤病例。胸部X线片显示右上肺不张。支气管镜检查发现右上叶支气管内有一个边界清晰的病变，几乎完全阻塞，但未进行活检。CT扫描发现支气管内肿瘤，肿瘤内可见脂肪。诊断为支气管内脂肪瘤，并对右上叶支气管进行了袖状肺叶切除术。病理诊断为黏膜下脂肪瘤。在超过1年的随访期间，患者症状改善。CT扫描可用于诊断支气管内脂肪瘤，并有助于制定治疗方案。
