A case of unicentric Castleman's disease located in the mediastinum is
presented. A 20 years old male suffering from cough had an image of
right hilar enlargement on chest X-ray. Thorax CT revealed multiple
enlarged lymph nodes both in right paratracheal and hilar region.
Radionuclide accumulation was detected by 67Ga scintigraphy. Surgical
removal of lymph nodes at paratracheal region was performed by
mediastinoscopic excision and reported as reactive hyperplasia. Lymph
nodes located in right hilum was excised by thoracotomy and
histopathologic examination confirmed Castleman's disease. Our thought
about this case was a dominant infiltrative mass with an associated
lymphadenopathy. 67Ga scintigraphy imaging that we performed in our
case can be a useful method in detection of Castleman's disease
