Congenital bronchobiliary fistula: a case report and literature review

Congenital bronchobiliary fistula (CBBF) is a very rare malformation associated with clinical symptoms of dyspnoea, vomiting, cyanosis, persistent pneumonia, and poor response to antibiotics. Typical imaging techniques used to diagnose this malformation include bronchography, computed tomography (CT), cholangiography, hepatobiliary nuclear imaging, and magnetic resonance imaging (MRI). We diagnosed a case of CBBF that was initially diagnosed as non‐resolving pneumonia. CT and fistulography were used to obtain the correct diagnosis. The fistula was confirmed by fistulography under the guidance of bronchoscopy. Surgical excision of the fistulous tract was performed, with complete recovery. The aim of this report was to emphasize the epidemiology and clinical features of CBBF patients.
