Angio-Computed Tomography (ACT) was obtained with three phases: arterious (a), venous (b), and delayed (c) from the injection of contrast media. The ACT acquisition confirmed a 36 mm x 17 mm oval mass in the left popliteal fossa. This lesion presented contrast enhancement only in delayed acquisition (c) and so appeared to be a true venous aneurysm.

This lesion had presented contrast enhancement only in delayed acquisition (180 sec) and so appeared to be a true venous aneurysm(Figures 2 and 3).
