Miller TT, Staron RB, Koenigsberg T et-al. Sonographic detection of Baker's cysts: comparison with MR imaging. liquified hematoma in the popliteal fossa.It was first described by the Irish surgeon, Robert Adams (1791-1875) 14 in 1840 and its intra-articular origin was described by William Morrant Baker (1839-1896) 6,12,13. compartment syndrome: can be either anterior or posterior.compression: of the popliteal vessels and tibial nerve.rupture: leaking of cyst fluid into the popliteal fossa, between fascial planes and surrounding the hamstrings and medial gastrocnemius muscles moreover, there is edema of the soft tissue and irregularity of the cyst wall.dissection: the cyst usually dissects inferomedially but can dissect proximally, anteriorly, intermuscularly or intramuscularly.If the symptoms persist and/or the cyst is very large, a surgical excision is an option. Aspiration may be performed, with steroid injection shown to be beneficial in reducing Baker cyst size and improving symptoms 5,6,10. In children, they can be common, with most spontaneously resolving within 10-20 months. usually anechoic, but may contain internal debrisĮxquisitely outlines the cyst as a mass extending from the joint space with high T2 signal content.this has been referred to as shaped like a " speech bubble" or " talk bubble" 11.identification of a fluid-filled structure at the posteromedial knee is suggestive of a popliteal cyst, but identification of the 'neck' between the tendons is necessary for a definitive diagnosis.well-defined cyst with a 'neck' at its deepest extent, extending into the joint space between the semimembranosus tendon and the medial head of the gastrocnemius.no connection, with primary gastrocnemius-semimembranosus bursitis.a valve-like connection between the knee joint and the gastrocnemius-semimembranosus bursa, resulting in fluid being squeezed in one direction.Two pathological processes are described 7: Symptomatic presentation may be acute when rupture occurs, in which case the chief differential diagnosis is deep venous thrombosis. A chronic/subacute presentation can manifest as a popliteal fossa mass or with pain. Associationsīaker cysts are most often found incidentally when the knee is imaged for other reasons. Two peaks are described: at 4-7 years and 35-70 years 7. ![]()
