Lumbar synovial cysts are an uncommon cause of back pain and radiculopathy, usually manifesting with gradual onset of symptoms, secondary to involvement of the spinal canal. Rarely, intracyst hemorrhage occurs, and may acutely present as radicular - or even spinal cord - compression syndrome. Synovial cysts are generally associated with degenerative facets, although the pathogenesis has not bee...
Cysts of the ligamentum flavum are uncommon causes of neurologic signs and symptoms and usually are seen in persons over 50 years of age. We report a case of an epidural cyst located in the ligamentum flavum, which contributed to spinal stenosis in a 30-year-old man. Radiologic features were similar to those of a synovial cyst, but synovium was not identified histologically. The imaging and pat...
Hydatid disease is a parasitic infection which occurs in specific geographical areas such as the Mediterranean region. We report a case of hydatid cyst of the knee in a 34-year-old man who was admitted with inability to walk and a painful knee. He had a past history of liver infection nine years ago. Laboratory findings were negative. According to the high prevalence of hydatid disease in Iran,...
A Baker’s (popliteal) cyst is a distention of the gastrocnemius–semimembranous bursa of the knee, which communicates with the posterior portion of the joint capsule. It usually appears in the popliteal fossa as a painless swelling. In adults it is nearly always secondary to pathological changes in the knee joint that cause an effusion. Occasionally the cyst becomes so large that it ruptures, sp...
BACKGROUND Facet degeneration often leads to the formation of synovial facet cysts. As facet cysts invade the spinal canal, they become a contributing factor to spinal stenosis. Previous studies have demonstrated successful treatment of neurogenic intermittent claudication (NIC), a major symptom of spinal stenosis, with an interspinous process device. PURPOSE To compare clinical outcomes of p...
The presence of a Baker's cyst may diminish the therapeutic effect of intra-articular 90Y treatment to the knee joint. SPECT (single photon emission computed tomography) was used in 10 patients with Baker's cysts, treated with intra-articular 90Y for persistent synovitis of the knee, to measure the amount of radioisotope within the cyst. Comparison was made with the arthrographic appearances. T...
CONTEXT Popliteal synovial cysts, also known as Baker's cysts, are commonly found in association with intra-articular knee disorders, such as osteoarthritis and meniscus tears. Histologically, the cyst walls resemble synovial tissue with fibrosis evident, and there may be chronic nonspecific inflammation present. Osteocartilaginous loose bodies may also be found within the cyst, even if they ar...
Synovial lipomatosis is an extremely rare type of disease in which there excess adipose tissue involving the synovium layer joints or synovial sheath around tendons causing pain, paraesthesia, and weakness. The most common site being reported till now Knee joint parapatellar space other such as elbows shoulders are after knee joint, ankle rarely 2 cases have been English literature. We report a...
Cutaneous metaplastic synovial cyst (CMSC), presents as a solitary, tender subcutaneous nodule that usually occurs at the site of previous surgery or trauma. Histologically, the lesion is characterized by a cystic structure with villous-like projections that lined by metaplastic synovial tissue. The main cause remains unclear, but trauma is presumed to be a precipitating factor, as most reporte...
