Cystic lesions in the wall of the popliteal artery with resulting collapse of the lumen.
The MRA shows a short segmental occlusion of the P1-segment.
Multiple ganglion cysts in the popliteal fossa. A small tubular connection between the ganglion cysts and the adventitiat of the politeal artery can be seen in the axial PDfs.
Cystic adventitial disease is a rare vascular condition with rapidly progressing claudication like symptoms.
A collection of mucinous material can be seen within the adventitial wall of the affected vessel.
This case nicely illustrates a tubular connection between the politeal ganglion cysts and the cystic adventitia, as suspected cause for the degeneration of the popliteal artery.
