  • Ganglion cyst

    serch.it?q=Ganglion-cyst

    A ganglion cyst is a fluid filled lump associated with a joint or tendon sheath. They most often occur at the back of the wrist followed by the front of the wrist. Onset is often over months. Typically there are no further symptoms. Occasionally pain or numbness may occur. Complications may include carpal tunnel syndrome. The cause is unknown. The underlying mechanism is believed to involve an outpouching of the synovial membrane. Risk factors include gymnastics. Diagnosis is typically based on examination with light shining through the lesion being supportive. Medical imaging may be done to rule out other potential causes. Treatment options include watchful waiting, splinting the affected joint, needle aspiration, or surgery. About half the times they resolve on their own. About 3 per 10,000 people newly develop ganglion of the wrist or hand a year. They most commonly occur in young and middle aged females. Trying to treat the lesion by hitting it with a book is discouraged.

  • Baker's cyst

    serch.it?q=Baker's-cyst

    A Baker's cyst, also known as a popliteal cyst, is a type of fluid collection behind the knee. Often there are no symptoms. If symptoms do occur these may include swelling and pain behind the knee, or knee stiffness. If the cyst breaks open, pain may significantly increase with swelling of the calf. Rarely complications such as deep vein thrombosis, peripheral neuropathy, ischemia, or compartment syndrome may occur. Risk factors include other knee problems such as osteoarthritis, meniscal tears, or rheumatoid arthritis. The underlying mechanism involves the flow of synovial fluid from the knee joint to the gastrocnemio-semimembranosus bursa, resulting in its expansion. The diagnosis may be confirmed with ultrasound or magnetic resonance imaging (MRI). Treatment is initially with supportive care. If this is not effective aspiration and steroid injection or surgical removal may be carried out. Around 20% of people have a Baker's cyst. They occur most commonly in those 35 to 70 years old. It is named after the surgeon who first described it, William Morrant Baker (1838–1896).
