MRI FINDINGS OF CONCURRENT ACUTE DVT AND DISSECTING POPLITEAL CYST

A case of concurrent popliteal vein thrombosis and a dissecting poplit eal cyst noted on the same MRI exam is described. Pseudothrombophlebit is is a well known entity in which a ruptured or dissecting popliteal cyst clinically mimics thrombophlebitis; the current case can be consi dered ''pseudo-pseudo thrombophlebitis.'' This case demonstrates the i mportance of routine review of the venous structures of the posterior fossa for all MRI exams of the knee.
