Gray-scale and color Doppler sonographic findings in a case of mesenteric Castleman's disease incidentally detected in a patient with Graves' disease.

We report a case of localized Castleman's disease of mesentery, studied with sonography, that was incidentally detected as an abdominal mass in a patient with Graves' disease. Its lymphatic nature and mesenteric origin was indicated preoperatively on the basis of gray-scale and color Doppler sonographic features.
