title: Baker's cyst and venous thrombosis.
abstract: A patient with deep venous thrombophlebitis had superficial thrombophlebitis while receiving adequate anticoagulation therapy and was then found to have a large Baker's cyst. The patient responded well to intra-articular steroids. Although an uncommon situation, thrombophlebitis may coexist with "pseudothrombophlebitis." Diagnosis requires a high index of suspicion and daily assessment of response to therapy.
