INTRODUCTION Synovial cyst is a rare cause of compression neuropathy and its differential diagnosis can be misleading. PRESENTATION OF CASE This article presents clinical, radiological, and histological findings of deep peroneal nerve palsy due to compression of a synovial cyst in a 30-year-old patient admitted with sudden drop foot. DISCUSSION Focal nerve entrapment in lower extremity due ...

Study Design Case report. Objective Synovial cysts in the subaxial cervical spine are rare and are most commonly reported at the cervicothoracic junction. Only six cases of symptomatic C5-C6 synovial cysts have been reported in the literature; the condition is usually treated with decompressive laminectomy. We present a patient with a synovial cyst arising from the C5-C6 facet joint, associated...

VOL. 71-B, No. 1. JANUARY 1989 Both RH and FH underwent arthrotomy and synovectomy. Multiple free osteochondromatous bodies were removed as well as several smaller ones attached to the synovium. The histology of the synovium in both cases was similar, showing metaplastic foci of cartilage in the synovial tissue beneath the lining layer, typical of synovial chondromatosis. Some areas were underg...

BACKGROUND This study was aimed to evaluate the prevalence of metaplastic changes in the epithelium of radicular cysts and to investigate how they relate to the clinical and radiographic characteristics of the cysts, based on a large series of radicular cysts. MATERIAL AND METHODS Biopsies of cysts of endodontic origin that were examined at the Department of Oral Pathology between 2004 and 20...

Primary synovial chondromatosis is an uncommon, benign entity involving the synovial lining of larger joints. In this metaplastic process, islands of chondrocytes are clustered throughout the synovium, forming nodules that jut into the joint cavity. Clinical manifestations include pain, swelling, and decreased range of motion of associated extremities. Synovial chondromatosis may be confused wi...

A case of congenital bronchogenic cyst in the gastric mucosa is presented. The cyst was lined by pseudostratified epithelium and covered with ciliated cells. Congenital bronchogenic cysts should be differentiated from acquired gastric cysts lined with ciliated metaplastic cells that evolve as a result of environmental factors.

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...

Intraspinal synovial cysts are infrequent causes of back and radicular leg pain. Commonly associated with degenerative spinal disease, the majority of synovial cysts appear in the lumbar spine. Rarely, intracystic hemorrhage can occur through an unclear mechanism. Similarly rare, cysts may also become migratory. The pathogenesis of hemorrhagic synovial cysts remains uncertain and their potentia...

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...

 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 a...
