Castleman disease rarely presents as an isolated retroperitoneal mass. We report two cases of retroperitoneal Castleman disease. Sonography showed hypoechoic mass. in two CT demonstrated homogeneously enhancing mass in two cases and calcifications in one case.

Castleman's disease (angiofollicular lymph node hyperplasia) is a large benign tumor. Most of the lesion are located in mediastinum, but some presents as an isolated retroperitoneal mass radiographically indistinguishable from retroperitoneal malignancy. We report a case of the hyaline-vascular variant of Castleman's disease presenting as a palpable abdominal mass.

Castleman's disease is characterized by the presence of a rare benign tumor of lymphoid origin which usually arises in the mediastinum but rarely occurs in the retroperitoneum. In the radiology literature, the unenhanced CT appearance of the disease has been decribed as hypodense or isodense as compared to that of the liver, and as showing homogeneous contrast enhancement. In this case, CT revealed a well-circumscribed, homogeneous enhancing mass with an internal cystic portion, a finding different from those described in the literature. We report a case of retroperitoneal Castleman's disease in which there was unusual mucoid degeneration resulting in a large cystic component, and which has not been previously reported.

Castleman disease is a benign disorder, usually occurring within mediastinum, characterized by proliferation of lymphold tissue. The authors report a rare case of Castleman disease originating from mesenteric root. The tumor was highly vascular, proved by dynamic CT examination and splanchnic angiography.

Castleman's disease or angiofollicular lymph node hyperplasia is a rare lymphoproliferative disorder. Complete surgical resection was recommended in unicentric Castleman's disease. Radiotherapy was considered alternative therapeutic option. However, there have been consistent favorable responses to radiotherapy. We also experienced two cases of uncentric Castleman's disease salvaged successfully with radiotherapy. This paper described these cases and reviewed the literature about Castleman's disease treated with radiotherapy. Reviewed cases showed that radiotherapy is a successful treatment option in unicentric Castleman's disease. Furthermore, our report confirms the radiotherapy role in uncentric Castleman's disease.
