BACKGROUND Tibial mononeuropathy due to compression by a synovial cyst is uncommon with fewer than 10 cases reported in the literature. METHOD Case Study. RESULTS Tibial motor mononeuropathy with focal conduction block between the popliteal fossa and ankle was identified by electrophysiological testing. Magnetic resonance imaging and surgical exploration identified a synovial cyst compressi...

In a case of juvenile rheumatoid arthritis with large synovial cysts, cyst fluid aspiration was performed to relieve pain, but recurrence was prevented with salicylate therapy alone. The mechanism of formation of synovial cysts is discussed.

BACKGROUND Intraspinal synovial cysts of vertebral facet joints are uncommon cause of radicular pain as well as neurological deficits. They can be managed both conservatively and surgically. CASE REPORT A 77-year old polymorbid patient presented with bilateral low back pain which worsened during the course of time and did not respond to the conservative treatment. A diagnosis of intraspinal s...

Synovial cysts occur secondary to injury, mucinous degeneration or tumours. We report a patient with snapping of the knee joint caused by a synovial cyst located near the patellofemoral joint which developed as a result of minor trauma.

A patient is described with rheumatoid arthritis and a painful synovial cyst, which originated from a metatarsophalangeal joint and presented as a swelling on the plantar surface of the foot. The cyst was successfully excised.

A 68-year-old female had a three-week history of severe low back pain radiating down the posterior left buttocks and left leg exacerbated by standing and walking. Lumbar spine MRI revealed cystic mass with similar intensity to cerebrospinal fluid located on dorsolateral left side of the sacral spinal canal inferior to the S1 pedicle. There was compression of left exiting S1 and traversing S2 ne...

Synovial cysts of the cervical spine, although they occur infrequently, may cause acute radiculopathy or myelopathy. Here, we report a case of a cervical synovial cyst presenting as acute myelopathy after manual stretching. A 68-year-old man presented with gait disturbance, decreased touch senses, and increased sensitivity to pain below T12 level. These symptoms developed after manual stretchin...
