Cervical spinal synovial and/or ganglion cysts can occur at various periarticular sites and should be considered in the differential diagnosis of intraspinal-extradural or paraspinal masses of the cervical spine. The first report of a ganglion cyst of the cervical anterior longitudinal ligament presenting as a retropharyngeal mass, is presented. The histopathology, etiology, and clinical aspect...

INTRODUCTION The purpose of this study is to report the findings resulting from chiropractic care using flexion distraction spinal manipulation for a patient with low back and radicular pain due to spinal stenosis caused by a synovial cyst. CASE REPORT A 75-year-old man presented with low back pain radiating to the right anterior thigh and down the left posterior leg of 3 years' duration. Phy...

Purpose: To report a quite rare case of bilateral symptomatic synovial cysts of the lumbar spine. Surgical resection is usually the cure for this condition. Methods: A 65 year old female patient came to our department, complaining for severe lumbar and sciatic pain. MRI and CT were used to diagnose bilateral synovial cysts. Because of the intensity of symptoms, she was subjected to surgery. Lam...

Synovial cysts of the cervical spine are extremely rare. We describe an 8-year-old boy with atlantoaxial subluxation and hypoplasia of the dens. Magnetic resonance imaging showed a round lesion, posterior to the odontoid process. This mass was characterized by a low signal intensity on T1-weighted images, and high signal intensity on T2-weighted images. The retrodental synovial cyst disappeared...

hands. Rheumatoid arthritis was diagnosed and she was treated with phenylbutazone, indomethacin suppositories, and gold injections. A tense swelling developed behind the right knee 6 months later. She was referred to a general surgeon and an initial diagnosis of fibrosarcoma was made. However, at operation, a synovial popliteal cyst was found and removed. After this, synovial fluid began to lea...

An 89 year old gentleman awaiting surgery for carcinoma of caecum presented with sudden back pain and developed foot drop two weeks later. MRI revealed multiple spinal metastases with a cyst in the canal at L4/5 causing spinal canal stenosis. Surgery revealed a juxta articular synovial cyst with haemorrhage in it. We discuss the presentation and management of juxtarticular cysts with a review o...

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...
