Table 3 Radiological characteristics of Castleman's disease
From: Surgical management of abdominal and retroperitoneal Castleman's disease
| Â | Non specific signs | Specific signs |
|---|---|---|
Radiography | calcification. | Star-shaped calcification. |
Echography | Hypoechogenic and homogenous mass. Central areas of acoustic shadowing (calcification). | Â |
CT scanner | Tissue density, Homogenous and well delimited mass. Contrast enhancement beginning in periphery. | Star-shaped microcalcifications Star-shaped scar on post-contrast study. |
Arteriography | Hypervascularity with hypertrophied feeding vessel. | Flush beginning in periphery to become diffuse and homogenous during capillary phase. |
MRI | Hypodense on T1 and hyperdense on T2. Contrast enhancement beginning in periphery. | Star-shaped microcalcification or star-shaped hypodense signal on T2. |
