Bronchial carcinoid tumors

Abstract

A retrospective evaluation was performed of radiographs obtained in 49 cases of bronchial carcinoid at presentation and during a follow-up period of 12 years. Histologic diagnosis from the surgical specimen was available in all cases. Carcinoids appeared most frequently (77%) as round or oval opacities with sharp and often notched margins. They often induced airway compression with pulmonary atelectasis; enlarged hilar lymph nodes from metastasis were rare. Recurrence after surgical removal was not frequent; the recurrent masses had the same radiographic features as the original tumor. The diagnosis of bronchial carcinoid must be taken into consideration when a slowly growing radiopaque mass with well-defined margins is discovered on chest films. The radiologist must remember that these tumors can be resected with a fairly good prognosis even when they are large.
