Introduction: Baker’s cyst is a common problem faced by orthopaedicians in day to day practice.  It could be due to various intra–articular pathologies like meniscal tears, chondral lesions, inflammatory arthritis and anterior cruciate ligament tears. When significantly large in size it can mimic in its presentation like pseudothrombophlebitis and might pose a confusing picture for the treating doctor. This is the first time in literature that we are publishing such a gigantic Baker’s cyst presenting as pseudothrombophlebitis.

Purpose: to stress importance about rare presentation of baker’s cyst in the form of pseudothrombophlebitis.

Conclusion: it is important to be suspicious about pseudothrombophlebitis in cases with giant baker’s cyst as it might be one of the presenting complaints in these patients. Also it is of utmost importance to assess and address intraarticular pathology in cases of baker’s cyst so as to prevent its recurrence in future
