Lumbar synovial cyst arises from the facet joint and can lead to back pain, radiculopathy, neurogenic claudication or even cauda equina syndrome. Although most surgeons would consider surgery to be the treatment of choice, the natural history of the disease process remains unknown and uncertainty still exists regarding optimal management of this controversial entity. We illustrate a case of lar...

excised ganglion resemble that of synovial membrane. However, it is generally accepted that if a synovial herniation becomes loculated as in a Baker’s cyst, the lining membrane can undergo a metaplastic change to mesothelium. \Vhile the predisposing factors responsible for the formation of ganglia are by no means certain, accumulated evidence suggests that trauma to the joint ma\’ be important,...

Two popliteal swellings, thought initially to be synovial cysts associated with arthritic knees, were found to be unrelated tumours of serious significance. In the presence of neurological signs or a large cyst in association with a noninflammed knee joint a disease other than a simple synovial cyst should be considered.

Intraspinal synovial cysts are rare but they are being documented with increasing frequency due to improvements in radiological imaging. However, hemorrhage into synovial cysts is uncommon, and affected patients may present with acute onset radiculopathy. This type of hemorrhage is known to result from rupture of fragile neoangiogenic vessels in the cyst wall, due to a traumatic event or antico...

Spinal cord compressing syndrome due to synovial cyst (SC) of the thoracolumbar spine is a rare clinical condition. In this report we aim to heighten awareness of the thoracolumbar facet synovial cyst as a possible cause of thoracic myelopathy. The SC was removed thoroughly by laminectomy. The patient had an excellent recovery. The etiological and therapeutic aspects are discussed.

The aim of this case report is to present an unusual double synovial cyst that arose from the proximal tibiofibular joint compressing the peroneal nerve in the peroneal tunnel and was unrecognized at the beginning. According to the review of literature back to 1891, only 62 cases of cysts originating from the proximal tibiofibular joint (PTFJ) have been described. We report a case of a 32 year ...

abstract two cases (20 and 15 years old) of shoulder joint synovial chondromatosis were initially treated with arthroscopic debridement. one was further treated with a second arthroscopy and partial synovectomy (case 1) the second was fully treated by arthroscopic surgery (case 2). the postoperative control x- ray revealed no loose body and the joint was normal. one of the cases (case 1) was af...

Lumbar spine synovial cysts are becoming more frequent, and they are generally associated with degenerative lumbar spinal disease. They are common in lower lumbar lesions but rare in upper lumbar lesions. Several cases of hemorrhage into lower lumbar juxtafacet cysts after trauma or anticoagulation therapy have been reported in the literature. This article describes a case of subacute cauda equ...

Three German Shepherd Dogs that were presented for investigation of chronic unilateral hindlimb lameness and pain in the lumbosacral region were diagnosed with an intraspinal, extradural synovial cyst and reactive fibrosis protruding into the foramen of the lumbosacral articulation using magnetic resonance imaging and histology. This extradural mass compressed the nerve root in the foramen and ...
