An abdominal ultrasound was performed, which demonstrated a large heterogeneous, significantly vascularized mass anterior to the lower aorta (Figure 1).
Enhanced arterial-phase CT demonstrates a multilobulated, well-defined, highly vascularized large mass situated at the mesentery with several areas of hypodensity corresponding with central necrosis.

This large mass was being supplied by multiple branches of the inferior mesenteric artery (Figure 2).
Direct invasive angiography with SOS2 catheter in the inferior mesenteric artery. Panel a: angiogram demonstrates highly vascularized lesion with multiple areas of neoangiogenesis. Panel b: delayed angiogram shows enhancement of the lesion.

The patient was admitted for two separate sessions of transarterial embolization of the tumour (Figure 3) in an attempt to reduce its size and vascularity prior to open surgical resection.
