| To evaluate the characteristic sonographic findings of Baker's cyst and to find out the possible factors whichcan influence the decision of treatment plan we performed a retrospective analysis of ultrasonograms of 21 provedBaker's cyst in 20 patients. The cysts were ovoid (52%) or elongated (48%) in shape. In 90.5%, there was tail-likelapering end toward the joint space of the knee. In 19%, there was tail-like tapering end toward the joint spaceof the knee. In 19%, there was fine or coarse echogenicity within the cyst. The coarse internal echogenicity wasconfirmed as hemorrhage within the cyst. In 62%, the connecting stalk could be traced to the head of gastrocnemiusmuscle. It was sharp in 69.2% and blunt in 30.8%. Fifty percent of cysts with blunt connecting stalk developedpost-operative recurrence. In conclusion, ultrasonography of Baker's cyst should be performed with specialemphasis on the internal echogenicity for the evaluation of the possible complication and on the connecting stalkfor the decision of the surgical approach. |
