21 lut 2023 · Baker cysts, or popliteal cysts, are fluid-filled distended synovial-lined lesions arising in the popliteal fossa between the medial head of the gastrocnemius and the semimembranosus tendons via a communication with the knee joint. They are usually located at or below the joint line.
13 wrz 2016 · Ruptured cysts often demonstrate fluid tracking deep to deep fascia and superficial to the medial head of the gastrocnemius (Fig 2d–e). In the acute phase there may be diffuse subcutaneous oedema and pain. At MRI, the cyst has fluid signal characteristics on all sequences.
These ganglion cysts are usually small and can easily be mistaken for normal anatomy on magnetic resonance imaging (ie, small periarticular vessel or fluid within the popliteus tendon sheath), leading to delayed patient diagnosis and appropriate treatment.
6 lip 2023 · Popliteal cysts in adults are often associated with osteoarthritis, inflammatory joint disease, or joint injury. They usually communicate with the adjacent knee joint space, especially in older patients with knee pathology; communicating cysts contain synovial fluid.

1 mar 2014 · It is important to be aware of the normal magnetic resonance (MR) imaging appearance of the popliteus musculotendinous complex and its relation to other structures of the posterolateral corner for accurate diagnosis. It is also important to be aware of the pitfalls in imaging of the popliteus.
Baker’s cyst, or popliteal cyst, is a fluid-filled mass that is a distention of a preexisting bursa in the popliteal fossa, most commonly the gastrocnemio-semimembranosus bursa.
