Abstract: Objectives To summarize the computed tomography angiography(CTA) features of Dieulafoy disease of the bronchus. Methods The clinical, imaging and pathological data of Dieulafoy disease of the bronchus diagnosed in our hospital from July 4, 2010 to June 20, 2016 were retrospectively analyzed, and the CTA imaging features of the abnormal bronchial arteries were summarized. Results There were 6 cases of bronchial Dieulafoy disease, 5 males and 1 female, with an average age of(55±15) years. Three cases had smoking history, and 2 cases had underlying diseases such as tuberculosis and acute myeloid leukemia. The common manifestations were hemoptysis, fever and pneumonia. Three patients got CTA examination, and bronchial arteries of Dieulafoy disease of the bronchus were circuitous and dilated, with the vascular diameter lager than 2 mm, no gradual narrowing but sudden truncation. Some circuitous vessels went into bronchial lumen as nodules. The bronchoscopy biopsy of 2 cases of bronchial nodules led to severe hemorrhage, with one death and one survival by successful management. Conclusions Bronchial arteries of Dieulafoy disease of the bronchus were circuitous and dilated, and some circuitous vessels went into bronchial lumen as nodules, this demonstration can be used to diagnose Dieulafoy disease of the bronchus. For patients with hemoptysis, bronchial biopsy should only be performed after CTA examination if this disease is suspected.
