Giant bone cysts in rheumatoid arthritis.

Comparing bone mineral density in rheumatoid arthritis and psoriatic arthritis

Background: Changes in patients’ bone mineral density (BMD) is one of the problems in patients with rheumatoid arthritis, which can be due to the use of corticosteroid drugs to reduce patients' symptoms or due to the aging process in patients. In this study, we decided to compare BMD in patients with psoriatic arthritis and rheumatoid arthritis. Methods: This study as a cross-sectional descrip...

Unusual geodes ('bone cysts') in rheumatoid arthritis.

Giant granulomatous lesions of the femoral head and neck in rheumatoid arthritis.

Local areas of subarticular bone erosion occurring in rheumatoid arthritis are a typical manifestation of the disease (Cruickshank, Macleod, and Shearer, 1954; Steven 1949). Occasionally they may be large enough to produce mechanical weakness, although the majority of spontaneous fractures in rheumatoid arthritis occur through uneroded areas of bone (Badley and Ansell, 1960). Such large osteoly...

Demonstration of a geode by magnetic resonance imaging: a new light on the cause of juxta-articular bone cysts in rheumatoid arthritis.

The magnetic resonance imaging (MRI) features of a rheumatoid arthritic geode are presented. Development of such a cyst from before x ray diagnosis to its coalescence with the wrist joint is described. The evidence suggests that these juxta-articular cysts are not merely an intrusion of the synovial cavity into the bone marrow but start as isolated structures beneath the subchondral bone.

A Case of Lipomembranous Panniculitis Associated with Rheumatoid Arthritis

Lipomembranous panniculitis is a special type of fat necrosis which has been associated with several clinical conditions, mainly chronic venous insufficiency and connective tissue disorders such as lupus profundus, morphea, systemic sclerosis, and dermatomyositis .We report a 50 yearold woman with known rheumatoid arthritis who presented with a painful indurated erythematous plaque on her right...
