[Pseudo-thrombophlebitis syndrome: diagnostic and therapeutic considerations of 2 cases].

Pseudo-thrombophlebitic syndrome is a frequent clinical entity but many times insufficiently diagnosed. Described more than a century ago by Baker it is characterized for being clinically undistinguishable from a true thrombophlebitis, being its cause the presence of a synovial cyst in the knee joint (Baker's cyst) which can be complicated or not (breakage or dissection). Diagnosis is easy and is based mainly in echography and arthrography. The anticoagulant therapy used in true thrombophlebitis is contraindicated in this syndrome.
