  Figure 1 The discrepancies among imaging modalities and surgical finding in patient with cystic adventitial disease. Total occlusion of the right PA was suspected on a volume-rendered three-dimensional CT image (A) but popliteal aneurysmal dilatation occluded by a hypoattenuating filling defect was revealed on a contrast-enhanced CT axial image (B). On contrary to the CT finding, a conventional angiography revealed no significant stenosis at the lesion (C). The IVUS revealed no definite atherosclerosis but extravascular hypoechoic lesion compatible with a cyst (D). Finally, the T2-weighted MRI revealed that multi-lobulated cysts (E, arrowheads) extending from the articular surface to the PA (E, arrow) encompass the PA circumferentially. After excision of the cystic wall (F, arrowheads), the medial layer of PA (F, arrow) was exposed. CT = computed tomography; IVUS = intravascular ultrasound; MRI = magnetic resonance image; PA = popliteal artery.
