The cystic adventitial degeneration of the popliteal artery is an extremely rare pathology. We introduce the case of a male patient 38 years old, reached our observation for strict claudicatio intermittens, with free interval of 50 meters approximately. The execution of arterial Ecocolordoppler of the inferior limbs evidenced a round oval lesion surrounding the left popliteal artery. An AngioRMN of the aortic district and the inferior limbs found clogging of the left popliteal artery in its intermediate part for approximately 2 centimeters, with regular reopen of the part to goes them. A successive RM of the left knee confirmed the presence of an oval extrinsic lesion in proximity of the left popliteal artery. The patient therefore had surgical operation, finding the effective presence of a swelling around adventitial tunic, that was cut with spillage of gelatinous material and then totally removed. The popliteal artery appeared lacking in stenotic lesions and perfectly throbbing after cyst remove. The data in literature indicate that the treatment of choice in order to avoid recidivists consists in the simple removal of the cyst, if the artery is not obstructed, associated to flow restore by means of graft or bypass in clogging case. The endovascular treatment is burdened by a high percentage of recidivist in the short term.
