1/37. Calcified bodies in popliteal cysts: a characteristic radiographic appearance.Calcified bodies in popliteal cysts have a characteristic radiographic appearance which can be confirmed by arthrography. Calcified bodies may arise in the true joint due to trauma, arthropathy resulting in joint destruction, or synovial osteochondromatosis. These calcified loose bodies may pass into a popliteal cyst through posterior joint-bursal communications or can arise in a popliteal cyst by chondrometaplasia. Correct radiographic interpretation will exclude soft tissue tumors and vascular lesions as differential considerations. Management of these patients will be determined by the clinical circumstances since neither popliteal cysts nor synovial osteochondromatosis are necessarily symptomatic.- - - - - - - - - - ranking = 1keywords = chondromatosis (Clic here for more details about this article) |
2/37. Acral synovial chondrosarcoma.Acral chondrosarcoma is rare. Synovial chondrosarcoma is even rarer. Synovial chondrosarcoma arising without evidence of pre-existing or concurrent synovial chondromatosis is exceedingly rare. We present a case of acral synovial chondrosarcoma involving both sides of the metacarpophalangeal joint of the thumb in a 69-year-old man. Radiographically, the lesion mimicked gout. On MR imaging, the lobulated contours of the soft tissue mass suggested synovial chondromatosis. Histological examination revealed a chondrosarcoma, which on the basis of imaging findings we present as having arisen from the synovium. The tumor invaded a portion of the cartilage of the metacarpophalangeal joint and equally destroyed the bones of the distal metacarpal and base of the proximal phalanx of the thumb, while sparing the bony joint surfaces.- - - - - - - - - - ranking = 1keywords = chondromatosis (Clic here for more details about this article) |
3/37. Radiologic case study. MRI in the diagnosis of synovial disease.Fourteen patients with various synovial diseases were imaged using conventional radiographic techniques and MRI. We had five patients with synovial tumors, including two each with PVNS and synovial osteochondromatosis. We had five patients with infections and four patients with various other forms of arthritis. Although MRI was found to be a useful means to visualize the synovium, the findings were nonspecific except in the case of PVNS.- - - - - - - - - - ranking = 0.5keywords = chondromatosis (Clic here for more details about this article) |

5/37. Extraskeletal chondromas.1. Extraskeletal chondromas occur in three variants: (a) as multiple nodules of synovial chondromatosis within a joint, (b) as a solitary lesion in association with articulations, within or adjacent to them, and (c) as an isolated cartilagenous lesion in the soft tissues, mostly of the hands and feet. 2. There are no histological characteristics which could differentiate articular, para-articular and soft tissue chondromas among themselves. 3. The latter two groups of extraskeletal chondromas are rare and frequently exhibit areas of immature cartilage with worrisome histologic features which could mislead the pathologist to an overdiagnosis of chondrosarcoma. 4. As a general rule, no matter how worrisome the histologic appearance of an extraskeletal, well delimited cartilagenous tumor may be, metastasis have not been recorded. Local recurrences are not infrequent after inadequate surgical removal; however, the tumor can always be controlled by adequate wide re-exision or resection. 5. Two cases of extraskeletal chondromas, one para-articular in the knee and the other in the soft tissue of the arm, have been presented with an exhaustive review of the literature on the subject. 6. It is of interest to note that our para-articular chondroma represents the first case reported in the literature where computerized tomography was utilized in the diagnosis. 7. The location of a soft tissue chondroma in the upper arm is extremely rare and only one previous case has been reported in said location.- - - - - - - - - - ranking = 0.5keywords = chondromatosis (Clic here for more details about this article) |
6/37. Pied piper syndrome--case report.A previously unreported involvement of the temporomandibular joint in a patient with a confirmed diagnosis of synovial osteochondromatosis is described. While etiology is not addressed, suggestive explanations for the clinical symptoms and possible recurrence prevention have been expanded upon. Despite confirming evidence, the author feels that this process may have both an urban and rural manifestation. However at present, the only references have appeared in the ancient literature of Aesop and Grimm.- - - - - - - - - - ranking = 0.5keywords = chondromatosis (Clic here for more details about this article) |
7/37. Arthroscopic observation and treatment of synovial chondromatosis of the temporomandibular joint. Report of a case and review of the literature.Synovial chondromatosis of the TMJ is a rare disorder of unknown etiology that may be neoplastic or hyperplastic in nature. A histopathologically confirmed case, the first to be identified and treated by arthroscopy, is presented. Removal of the affected synovial tissue and of loose particles was accomplished arthroscopically, a relatively non-invasive alternative to open arthrotomy.- - - - - - - - - - ranking = 2.5keywords = chondromatosis (Clic here for more details about this article) |
8/37. Synovial chondromatosis of the temporomandibular joint: report of two cases.Two cases of synovial chondromatosis of the temporomandibular joint are reported. This condition is rare but benign, with only 36 cases reported in the literature to date. Symptoms include tenderness, swelling, and limited range of motion, with deviation to the affected side. diagnosis is made both from the clinical presentation and histologic examination. The etiology is thought to be cartilaginous foci within the synovial membrane that become detached and proliferate in the synovium as chondrocytes. Treatment includes removal of the "loose bodies" and possible resection of the synovial membrane, condyle, and disk.- - - - - - - - - - ranking = 2.5keywords = chondromatosis (Clic here for more details about this article) |
9/37. The aetiology of multiple loose bodies. snow storm knee.We report four patients who showed hundreds of brilliant white loose bodies at arthroscopy of the knee after a short history of pain and crepitus. Histological, historical and clinical evidence is presented which indicates that the aetiology of this condition is the culture of chondrocytes in synovial fluid. It is suggested that reversal of the usually accepted order of events in synovial osteochondromatosis could provide a better and unified explanation for both that condition and multiple loose bodies. The term 'snow storm knee' is proposed to describe the dramatic picture seen at arthroscopy.- - - - - - - - - - ranking = 0.5keywords = chondromatosis (Clic here for more details about this article) |
10/37. Villonodular synovitis with synovial chondromatosis.Pigmented villonodular synovitis and synovial chondromatosis are uncommon benign lesions involving the articular surfaces of diarthrodial joints. Reported is a case of a benign synovial lesion of the temporomandibular joint, which was clinically thought to be a malignant parotid compartment tumor, showing histologic features of both pigmented villonodular synovitis and synovial chondromatosis. A review of the literature reveals a single case in which cartilaginous bodies were found in the joint; however, the synovial tissue showed features of only villonodular synovitis, with no mention of cartilaginous foci.- - - - - - - - - - ranking = 3keywords = chondromatosis (Clic here for more details about this article) |
