a: B-mode ultrasound image with a 8.1 cm heterogeneous mass located above the left psoas muscle. b: duplex image show vascularity within the mass and central hypoechoic areas without detectable vascularization. c: Axial CECT image show an intra-abdominal contrast enhancing tumour, with non-enhanced central areas, located medial to the descending colon (white arrow), anterior to the left psoas muscle. d: Follow-up axial CECT image 24 months after surgery show local tumour recurrence (yellow arrow).

A transabdominal ultrasound examination demonstrated an intra-abdominal oval shaped heterogeneous mass measuring 6.5 x 5.5 x 8.1 cm with respect to the surrounding structures (Fig. 1a). Colour Doppler showed several intra-tumoural vessels as well as central hypoechoic areas without detectable Doppler signal (Fig. 1b). The CECT showed a tumour located concordant to the ultrasound finding, beneath the abdominal wall, medial to the descending colon, anterior to the psoas muscle (Figs. 1c and 2 ). Follow-up CECT after 24 months showed a solitary contrast-enhancing tumour measuring 1.8 x 2.3 x 2.3 cm, at the location of the original tumour (Fig. 1d).
Coronal CECT image show an intra-abdominal contrast enhancing tumour, with non-enhanced central areas, located medial to the descending colon, lateral to the aortic bifurcation (yellow arrow).
