Computed tomography of the thorax showed a soft tissue density nodule with spiculated margins and vascular convergence in the lower lobe, measuring 3 x 2 cm, in the right lung.

CT of the thorax showed a soft tissue density nodule with spiculated margins and vascular convergence in the lower lobe, measuring 3 x 2 cm, in the right lung (Figure 1).
A right retrograde ureterogram showed a continuous extrinsic obstruction of the middle third of the ureter (arrowheads).

A right retrograde ureterogram showed a continuous extrinsic obstruction, 7 cm in length, of the middle third of the ureter (Figure 2).
(a) T1-weighted magnetic resonance images demonstrated a retroperitoneal mass (arrowheads) with compression of the inferior vena (arrow). (b) Contrast-enhanced T1-weighted image showed the mass in a ring-like fashion.

T1-weighted magnetic resonance images demonstrated a retroperitoneal mass, measuring 3 x 3 x 5 cm, with compression of the inferior vena cava (Figure 3(a)). Enhancement by gadolinium-diethylenetetraminepentaacetic acid of the T1-weighted images showed a high-intensity rim (Figure 3(b)).
Pathological examination of the retroperitoneal mass indicated a poorly differentiated adenocarcinoma with fibrosis.

CT-guided fine needle biopsy of the retroperitoneal mass was performed, and the pathological examination indicated a poorly differentiated adenocarcinoma with fibrosis (Figure 4).
