1/94. Lumbar intraspinal synovial cysts of different etiologies: diagnosis by CT and MR imaging.Intraspinal synovial cysts arises from a facet joint and may cause radicular symptoms due to nerve root compression. In the present study, three surgically and histologically proved cases of synovial cyst of the lumbar spine with different etiology are described. The purpose of this report is to illustrate the imaging features of various etiologies of intraspinal synovial cysts allowing a correct preoperative diagnosis. review of the literature enables us to say that to our knowledge, there is no reported article collecting the imaging findings of intraspinal synovial cysts with different etiologies. Only single cases with rheumatoid arthritic or traumatic origin have been reported to date. We believe that computed tomography and particularly magnetic resonance imaging are the methods of choice which provide the most valuable diagnostic information.- - - - - - - - - - ranking = 1keywords = cyst (Clic here for more details about this article) |
2/94. Cystic rheumatoid arthritis with Felty's syndrome and ankylosing spondylitis.A 63-year-old man with strictly axial ankylosing spondylitis since the age of 28 years had a seven-year history of cystic seronegative rheumatoid arthritis with Felty's syndrome. cysts were present in the hands, feet, wrists, shoulders, hips, one elbow, and one knee. There was no evidence of juxtaarticular demineralization, joint space loss, erosions, or joint destruction. Rheumatoid pannus was demonstrated within the cysts, particularly at the hip, ruling out cystic hip disease due to ankylosing spondylitis. HLA typing demonstrated the B27 and DR4 haplotypes. HLA B27 may be associated with a worse prognosis of rheumatoid hip involvement.- - - - - - - - - - ranking = 0.375keywords = cyst (Clic here for more details about this article) |
3/94. Multiple rheumatoid bursitis with migrating chylous cysts. Report of a case in a European woman and review of the literature.We report a case of recurrent multiple bursitis (19 episodes at nine sites) requiring seven surgical procedures in a European women with a 38-year history of severe, nodular, destructive seropositive rheumatoid arthritis unresponsive to second-line drugs. The episodes of bursitis were not correlated with activity of the joint disease. Some cysts migrated over a considerable distance. At least two cysts contained chylous fluid. The histologic study of one cyst demonstrated a cholesterol crystal granuloma. Potential relationships linking cholesterol crystals, chylous cysts, and migrating multiple bursitis are discussed. The relevant literature is reviewed.- - - - - - - - - - ranking = 1keywords = cyst (Clic here for more details about this article) |
4/94. Multiple cutaneous metaplastic synovial cysts.The cutaneous metaplastic synovial cyst is a recently described lesion that characteristically presents as a solitary, tender subcutaneous nodule. On histopathologic examination, the lesion is characterized by a cystic structure with villous-like projections and a lining resembling hyperlastic synovium. The cause of cutaneous metaplastic synovial cysts is unclear, but trauma is presumed to be a precipitating factor, as most reported cases have a history of antecedent cutaneous injury. Here we present a case of multiple, bilateral cutaneous metaplastic synovial cysts in a 72-year-old white man with rheumatoid arthritis. This is the first reported case of a patient with multiple lesions. The characteristic clinical and pathologic features of this lesion, along with proposed cause, are reviewed herein.- - - - - - - - - - ranking = 1keywords = cyst (Clic here for more details about this article) |
5/94. Drug-associated cholelithiasis: a case of sulindac stone formation and the incorporation of sulindac metabolites into the gallstones.A case of drug-associated cholelithiasis (sulindac chlecystohepatolithiasis) in a 63-yr-old woman is reported. The patient was admitted to our hospital to undergo treatment for rheumatoid arthritis of 20 yr duration. She was treated with nonsteroidal anti-inflammatory drugs (NSAID: sulindac). Two months later, she presented with right upper quadrant pain. Diagnostic studies including ultrasonography (US), computed tomography (CT) and endoscopic retrograde cholangiography (ERC), led to the diagnosis of cholecystohepatolithiasis. She underwent cholecystectomy and choledochotomy with an extraction of intrahepatic stones. The intrahepatic stones were light yellow in color with a claylike appearance. Unexpectedly, an infrared spectroscopic analysis of the stone showed it to consist of sulindac metabolites. In addition, the dilated segment of the intrahepatic bile duct naturally returned to its normal size after the discontinuation of the drug administration. This is the first reported case of sulindac stone formation in the bile duct. No similar problems with other NSAIDs have been reported previously.- - - - - - - - - - ranking = 0.375keywords = cyst (Clic here for more details about this article) |
6/94. Posterior tibial neuropathy by a Baker's cyst: case report.Baker's cysts are rare cause of peripheral nerve entrapment and only a few cases of tibial nerve entrapment resulting from the popliteal cyst in the calf muscle have been reported in the literature. We present a case of rheumatoid arthritis complicated by a Baker's cyst with a tibial nerve entrapment. It is important to diagnose a Baker's cyst early and to differentiate it from thrombophlebitis, a popliteal aneurysm, tumor or muscle tear to effect optimal therapy and to obviate a potential neuropathy. Prompt recognition of these cases may save the patients unnecessary procedures and delay in treatment.- - - - - - - - - - ranking = 64.092761049217keywords = popliteal cyst, cyst (Clic here for more details about this article) |
7/94. Giant rheumatoid synovial cyst of the hip joint: diagnosed by MRI.Synovial cysts are commonly found in the knee joint. hip joint is an infrequent site for formation of synovial cysts. The features of a large, synovial cyst on magnetic resonance imaging, occurring in the hip joint, are described.- - - - - - - - - - ranking = 0.875keywords = cyst (Clic here for more details about this article) |
8/94. Multiple epidermal inclusion cysts in a patient with rheumatoid arthritis: a case report.A construction worker with rheumatoid arthritis presented with multiple soft tissue masses on the volar surface of the palm and digits. A misdiagnosis of rheumatoid nodules was made secondary to the patient's history of rheumatoid arthritis. Subsequent excision confirmed multiple epidermal inclusion cysts, which was not entertained in the preoperative differential diagnosis. Follow-up evaluation 3 years later revealed no evidence of local recurrence. Based on our literature review, multiple epidermal inclusion cysts is a rare entity and has not been reported in a patient with rheumatoid arthritis.- - - - - - - - - - ranking = 0.75keywords = cyst (Clic here for more details about this article) |
9/94. Thoracoscopic resection of the pulmonary aspergilloma: report of two cases.Pulmonary aspergillomas causing hemoptysis were successfully resected through videothoracoscopy in two cases. We removed an aspergilloma located in the right lower lobe of the lung in a 48-year-old woman with a bronchial cyst and rheumatoid arthritis. We also removed an aspergilloma located in the left upper lobe of the lung in a 59-year-old man with emphysematous bullae and diabetes mellitus. In both cases, the aspergillomas were removed by pulmonary wedge resection through scheduled thoracoscopy.- - - - - - - - - - ranking = 0.125keywords = cyst (Clic here for more details about this article) |
10/94. quadriplegia in a case of known rheumatoid arthritis.Rheumatoid arthritis often involves the axial skeleton. rheumatoid nodule, often a manifestation of rheumatoid arthritis may be present in 20-30% of patients of rheumatoid arthritis. A 69-year-old male was presented with weakness of all the four limbs. He had history of rheumatoid arthritis for last 10 years. On examination, a soft cystic non-compressible lump was found over sacrum. Histopathological examination of the lump showed some changes which were consistent with the changes occur in rheumatoid nodule. The patient was treated conservatively and keeping well after 3 months of follow-up.- - - - - - - - - - ranking = 0.125keywords = cyst (Clic here for more details about this article) |
