In a computerised tomographic scan (CT) there can be seen a 3 x 5 cm retroperitoneal tumour in contact with the aorta and the inferior vena cava, with a homogenous uptake of the contrast medium (Fig. 1).
MRI showing a retroperitoneal node, with an increase in signal in the potentiated sequences in T2 and restriction to the diffusion and enhancement with contrast.

T2 and restriction to the diffusion and enhancement with contrast medium (Fig. 2). The study was completed with a scintigraphy with somatostatin receptors (OctreoScan) SPECT CT in which the retroperitoneal mass shows a pathological uptake.

Accessing it through the right femoral artery, a selective angiography of the right lumbar arteries was carried out, being able to complete the vascularization of the tumour by direct branches from the distal third of the aorta (Fig. 3).
arteriography from the upper mesenteric artery showing small arterioles that rise from the ileocolic artery and irrigate the tumour.

It had a nodular appearance and a brownish colour and was closely adhered to the distal aorta, the right iliac artery and the inferior vena cava at the level of the confluence of the iliac veins, but without infiltrating it (Fig. 5).
