Castleman`s disease is an uncommon lymphoproliferative disorder which can occur wherever lymph nodes are present. Castleman`s disease in the chest develops usually in mediastinal or hilar lymph node. A 53-year-old woman was admitted to our hospital for further evaluation of a pulmonary nodule detected incidentally in health check-up. Computer tomography demonstrated that this nodule was 27 × 25 mm, well-defined in the right upper lobe. On MRI of chest MRI, which was performed to further diagnosis, the nodule was located on perihilar area of the right upper lobe and showed high signal intensity in T2 weight imaging and rapid and strong enhancement in dynamic contrast image, suspected to be a sclerosing hemangioma. We performed right upper lobectomy with lymph node dissection and the pathologic examination revealed that the pulmonary nodule was Castleman`s disease arising from an intrapulmonary lymph node. We here report a rare case of Castleman`s disease in intrapulmonary lymph node presenting as solitary pulmonary nodule, suggesting that Castleman`s disease should be considered in patients with a nodule in perihilar area.
