Fig. 1.
A 46-year-old woman with rheumatoid arthritis and ruptured and dissected baker cyst. Ultrasonogram shows typical location of the baker cyst in the space between the medial head of the gastrocnemius and semembranosus (A). Anechoic dissected baker cyst with internal synovial proliferation demonstrates in the space between the medial head gastrocneiums and superficial fascia (B). Coronal fat suppressed T2-weighted MR image show high signal intensity of baker cyst with rupture and dissection into the space between the medial head gastrocnemius and superficial fascia. There is an extension into the subcutaneous tissue layer (C, arrow).
Fig. 2.
A-72-year old woman with rheumatoid arthritis and ruptured and dissected baker cyst. Axial T1-weighted MR image (A), T2-weighted image (B), and coronal sagittal fat-suppressed image (C) show ruptured and dissected baker cyst, appearing with heterogeneous high signal intensity due to internal synovial proliferation and hemorrhage within the gastrocnemius muscle and space between the superficial fascia and the both head of the gastrocnemius muscle (arrow).
