Endobronchial lipoma with obstructive pneumonia: A case report

Endobronchial lipoma (EL) is a rare benign lung tumor, and its incidence rate only accounts for a tiny proportion of all lung tumors. EL has non-specific clinical symptoms and signs, and chest computed tomography is helpful in diagnosis. When fat density nodules are found in the bronchial lumen with no enhancement, EL should be considered. Once this disease is diagnosed, bronchoscopic intervention therapy is the first choice for treatment, and patients generally have a good prognosis. The present report describes the diagnosis and treatment processes of a patient with EL. The patient sought medical attention due to recurrent fever, cough and white sputum for >1 month. The chest CT revealed a hypodensity nodule at the bronchial opening of the basal segment of the lower lobe of the left lung, with the margins showing foci of punctate calcification. The patient underwent a bronchoscopy and the pathological diagnosis was EL. In the present study, a literature review analysis is also included to provide a reference for the diagnosis and treatment of this disease.
