Abstract

To describe the CT findings of an endobronchial metastasis from a renal cell carcinoma (RCC). The CT findings and clinical features of a histologically proven endobronchial metastasis from a RCC in four patients (three male, one female; age range, 64-80 years; mean age, 69 years) were reviewed retrospectively. The location of the metastasis in the airway, shape, the degree of tumor enhancement, and the associated pulmonary parenchymal abnormalities were analyzed. The histological subtype of the endobronchial metastases from the RCC was conventional in all cases. The tumors were located at the lobar (n = 1), both the lobar and segmental (n = 2), or the segmental (n = 1) bronchus. On the CT scan, the tumors were polypoid (n = 1), had a glove-finger appearance (n = 2), and exhibited branching in the airways and bronchial wall thickening (n = 1). The endobronchial metastasis from the RCC showed very high attenuation (84-128 HU), and strong enhancement (51.6-93.3 HU) on the contrast-enhanced CT images. The lung parenchymal lesions that had reticular opacities and ground glass opacities (n = 3). An endobronchial metastasis from a RCC appears as a strong-enhancing mass or bronchial wall thickening, accompanied by reticular opacities a...Continue Reading
