1/7. Paratibial cyst associated with wear debris after total knee arthroplasty.We present a case in which a synovial cyst arose from the proximal tibia and expanded in the calf of a patient after total knee arthroplasty. A cystogram showed a direct communication between the joint cavity and the cyst, apparently associated with a screw that penetrated the tibial cortex. Histologic examination of the cyst showed an inflammatory reaction, including macrophages, foreign body giant cells, and metal and polyethylene particles. To our knowledge, this is the first case report illustrating a paraosseous cyst that developed after total knee arthroplasty. Wear debris from the total knee prosthesis may have been responsible for this unusual cyst.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
2/7. Giant synovial cyst of the calf and thigh in a patient with granulomatous synovitis.A giant synovial cyst with granulomatous synovitis was removed from the thigh and calf in an 80-year-old woman. The lesion included necrotizing, epitheloid cell granulomata with Langhans' type giant cells. Chest X-ray, tuberculin testing, cultures for Acid Fast bacilli, as well as aerobic, anaerobic and fungal cultures were all negative. The treatment consisted of synovectomy and total knee arthroplasty with an uneventful recovery. A giant calf cyst, usually associated with rheumatoid arthritis, but in this situation, noted in granulomatous synovitis seems not to have been reported previously.- - - - - - - - - - ranking = 3keywords = giant (Clic here for more details about this article) |
3/7. Giant intraosseous cyst-like lesions in rheumatoid arthritis report of a case.The term "intraosseous synovial cyst" is used to designate both the epiphyseal cyst-like lesions seen in patients with rheumatoid arthritis (RA) and mucoid cysts, which occur in a different setting. We report the case of a patient in whom a 4-cm cyst-like lesion developed in the left tibia 18 years after onset of RA and 6 years after osmic acid synovectomy of the left knee. Positive contrast arthrography and magnetic resonance imaging visualized a communication between the lesion and the joint space. Preexisting bone and joint lesions and increased intraarticular pressure play a major role in the genesis of cyst-like lesions in RA. In our patient, the osmic acid synovectomy may have contributed to the development of the lesion. "synovial cyst" is a misnomer for these giant lesions, which are geodes rather than cysts. Despite their low incidence, these lesions deserve attention because they raise diagnostic and therapeutic problems.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
4/7. A giant ganglion cyst that developed in the infrapatellar fat and partly extended into the knee joint.ganglion cysts of the knee joint usually present near the lateral meniscus. Their size varies, and they may be encased in single or multiple capsules. Few case reports on ganglion cysts of the knee joint have been reported. We report a giant ganglion cyst that developed in the patellar fat and partly extended into the joint. The ganglion cyst was exposed in the meniscosynovial junction and was electrically evaporated at the anterior horn. No recurrence has occurred to date, and the patient has returned to his previous level of activity.- - - - - - - - - - ranking = 5keywords = giant (Clic here for more details about this article) |
5/7. Bilateral giant cyst of the shoulder.The case of a 61 year old white female with a rapidly progressive rheumatoid arthritis who developed bilateral giant cyst of the shoulder is described here. Arthrographic investigation indicated that these giant cysts were true synovial cysts rather than "pseudocysts".- - - - - - - - - - ranking = 6keywords = giant (Clic here for more details about this article) |

7/7. Giant ganglion of the proximal tibiofibular joint: a case report.Ganglions of the tibiofibular joint are a rare condition. The exact tissue of origin could not be accurately determined despite the use of CAT scanning. At surgery a giant ganglion of the tibiofibular joint was resected with preservation of the peroneal nerve.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
