The patient was a 42-year-old woman. On an annual medical check-up in 1991, an abnormal shadow was detected in the right pulmonary hilum on chest X-ray film. Though the shadow did not change between 1991 and 1993, it gradually developed over the next eight years. Chest CT showed a 2.5×3.5× 3.0 cm tumor as a well-defined and homogeneous mass in the border between the right middle and inferior lobe bronchus. Chest MRI showed a hypointensive mass on T1-weighted image, a hyperintensive mass on T2-weighted image. The mass is strongly enhanced on contrast-enhanced CT and T1-weighted image. Tumor resection by video-assisted thoracoscopic surgery allowed diagnosis and treatment of the rare disease. Histopathological examination demonstrated hyaline vascular type of Castleman's disease. The developmental course of the disease over long-term observation is described.
