Abstract

|
Purpose: The goal of this study is to assess the usefulness of ultrasonography in diagnosis of Baker’s cyst.
Materials and Methods: 42 cases of popliteal mass in 41 patients were reviewed between August 2006 and April 2009. All patients were evaluated with both MR imaging and ultrasonography. We investigated the comparison of a morphology, location, septation, and communication of mass between MR imaging and ultrasonography.
Results: On ultrasonography, 40 Baker’s cysts and 2 lipomas were detected, and all cysts were located at the medial side. 11 simple septated masses and 3 multiple cysts were detected, and 26 simple communicated cysts were suspected. On MR imaging, 40 Baker’s cysts and 2 lipomas were detected, and all cysts were located at the medial side. 13 simple septated masses and 3 multiple cysts were detected, and 15 simple communicated cysts were suspected.
Conclusion: Ultrasonography didn’t give the definite information of Baker’s cyst about communication with joint, but ultrasonography was a cost-effective useful tool for evaluation of a morphology, location and differential diagnosis of the Baker’s cyst.
