title: Clinicopathological analysis of a case with mesenteric solitary Castleman's disease: diagnostic value of radiological findings.
abstract: We report a case with rare solitary mesenteric Castleman's disease (CD). A 45-year-old woman complaining of nausea was presented. A round-shaped, smooth margin, and hypoechoic mass was seen on screening abdominal ultrasonography. Computed tomography showed a markedly enhanced tumor anterior to the left iliopsoas muscle. Selective jejunal arteriography revealed an extreme hypervascularity without vascular invasion. These results retrospectively seem to differ from those of malignant lymphoma or sarcoma. The tumor was surgically resected, and hyaline-vascular type CD was pathologically diagnosed. We postulate that these radiological findings might suggest hyaline-vascular type CD as one of the differential diagnoses in similar cases, although more clinical data should be evaluated.
