¿QUÉ ES EL QUISTE DE BAKER O POPLÍTEO? ANATOMÍA, DIAGNÓSTICO, ECOGRAFÍA, TRATAMIENTO.

A Baker's cyst (popliteal cyst) is a fluid-filled sac in a bursa (sac) at the back of the knee. These cysts are relatively common and appear as a consequence of conditions that cause an increase in synovial fluid (any type of arthritis, including osteoarthritis, which can have episodes of knee inflammation). In other words, they are not the problem itself, but rather a consequence of another underlying issue, which is what must be treated to achieve a more comprehensive solution. Fortunately, these cysts are usually painless, and the patient can feel a lump behind the knee (popliteal fossa). Diagnosis is made through a thorough physical examination by a doctor, and an ultrasound is usually sufficient to visualize the cyst. However, sometimes they can cause pain at the back of the knee that worsens with walking and when flexing the joint. This occurs due to inflammation, rupture, bleeding, increased internal pressure, or compression of nearby structures. It must be differentiated from other diagnoses, including deep vein thrombosis (DVT) and myofascial pain in the muscles of the region. In these situations, Baker's cysts can be drained percutaneously under ultrasound guidance. It is a relatively quick and elegant procedure. The monitor shows the cyst "deflating" as it is aspirated. After the procedure, symptoms may disappear completely or at least be reduced. #Baker'sCyst #UltrasoundGuidedDrainage #PoplitealCyst
