Tumorthrombus bei Nierenzellkarzinom

Recurrent

malignant caval thrombosis: value of diffusion-weighted MRI. Portal venous phase acquisition confirmed right nephrectomy without local tumour recurrence in the surgical bed, normal left kidney with opacified renal vein (arrow), near-complete filling defect in the inferior vena cava (arrowheads).

Recurrent

malignant caval thrombosis: value of diffusion-weighted MRI. Coronal image confirmed sizeable filling defect (arrowheads) with 3.5 cm craniocaudal diameter causing minimal dilatation of the inferior vena cava; note unopacified (+) distal lumen due to acquisition before venous return from the extremities.

Recurrent

malignant caval thrombosis: value of diffusion-weighted MRI. On fat-suppressed T1-weighted images the thrombus (arrowheads) showed low-to-intermediate signal intensity, with speckled hypersignal foci (thin arrows).
