A Case Report of Thoracic Enhanced Chest CT Combined with Endobronchial Ultrasound for the Diagnosis of Asymptomatic Bronchial Dieulafoy's Disease
-
摘要: 本文报道1例采用胸部增强CT结合支气管内超声(endobronchial ultrasound, EBUS)诊断的罕见无症状支气管Dieulafoy病患者，胸部增强CT可见左主支气管内结节样新生物，动脉期部分强化，支气管镜检查示左主支气管远端结节样黏膜隆起，表面光滑，可见细小血管，未见搏动，未行活检，行EBUS探查病灶支气管黏膜下血流情况，可见明显彩色血流信号。根据上述表现考虑诊断为支气管Dieulafoy病。对于未发生咯血的患者，如支气管镜检查有主气道结节样新生物，可采用胸部增强CT结合EBUS明确诊断，避免盲目活检而导致致死性大出血，该方法无创、安全且有效易行，值得临床推广应用。

Abstract: We reported a rare case of asymptomatic bronchial Dieulafoy's disease diagnosed by enhanced chest CT combined with endobronchial ultrasound (EBUS). The enhanced chest CT showed nodular neoplasm in the left main bronchus and partial enhancement in arterial phase. Bronchoscopy showed nodular mucosal protrusion lesion at the distal end of the left main bronchus, and the protrusion lesion had smooth surface and no pulsation, with some microvessels on it, and obvious submocasal blood flow signals were seen by endobronchial ultrasound. The diagnosis of bronchial Dieulafoy disease was considered based on the above findings and biopsy was not performed. In patients without haemoptysis, if there are nodular neoplasms in the main airway on bronchoscopy, enhanced chest CT combined with EBUS can be used to diagnose bronchial Dieulafoy's disease and avoid fatal haemorrhage due to conventional biopsy. The method is non-invasive, safe and effective, and worthy of clinical application.-
