Periodontoid Synovial Cyst Causing Cervico-medullary Compression

A synovial cyst in the cervical spine causing acute spinal cord compression.

Thoracic Synovial Cyst at the Th2-3 Level Causing Myelopathy

Intraspinal synovial cyst is a rare cause of myelopathy. These cysts present most often in the lumbar and cervical parts of the spine but are more infrequent in the thoracic spine. We present a case of a 73-year-old man with an intraspinal, extradural synovial cyst at the Th2-3 level causing paraesthesia and weakness in the legs. A laminectomy and excision of the cyst were performed and the pat...

Synovial cyst of the high cervical spine causing myelopathy.

The authors describe the myelographic and postmyelographic CT findings of an extradural mass with cord compression in an 82-year-old woman. Synovial cysts generally occur posterolaterally and are associated with degenerative facet joints; an unusual site together with facet joint disease should alert the observer to the possibility of a synovial cyst.

Thoracic Intraspinal Synovial Cyst Causing Myelopathy: A Case Report

spine and less commonly found in the cervical spine (1). An occurrence of a cyst in the thoracic spine causing myelopathy is extremely rare (2) and to the best of our knowledge, 25 cases of thoracic synovial cyst have been reported in the English language clinical literature and of these cases, only seven cases have been reported where a synovial cyst was combined with myelopathy. These intrasp...

Huge cervico-thoracic thymic cyst.

We present a case of a 6 year-old boy who presented with a huge mass in the right side of the neck and changes its size with respiration and with straining. Computed tomography of the chest and neck showed a huge mass that was thought to be cystic hygroma. It was excised by both median sternotomy and a right cervical incision. Pathology revealed a thymic cyst.
