Synovial sarcoma Radiology

Synovial sarcomas detected at radiography typically appear as nonspecific, round to oval juxtaarticular soft-tissue masses. Calcification is identified in up to 30% of synovial sarcomas at radiography (, 1 43) (Figs, 2, 7,) Synovial sarcoma is the fourth most common type of soft-tissue sarcoma, accounting for 2.5%-10.5% of all primary soft-tissue malignancies worldwide. Synovial sarcoma most often affects the extremities (80%-95% of cases), particularly the knee in the popliteal fossa, of adolescents and young adults (15-40 years of age) Synovial sarcoma is the third most common soft-tissue sarcoma in adults, accounting for approximately 10% of soft-tissue sarcomas [ 1 ]. Men and women are affected equally, and the mean age at presentation is 32 years [ 2 ] MRI features of synovial sarcoma are of a well-defined heterogeneous soft tissue mass around joint, more specifically, near to the tendon, bursa or around the joint capsule. The triple sign is classically described in synovial sarcoma which is a mixture of high, intermediate and low signal regions within the mass seen on T2 weighted images Synovial sarcomas are usually first detected as painless growing masses. 14 Confirmation of the presence of a mass by radiography and MRI is usually performed prior to biopsy. 14 Definitive SS diagnosis is based on biopsy

Synovial sarcoma is the most common malignant nonrhabdomyosarcoma soft-tissue sarcoma in children. This article shows examples of synovial sarcoma in children and corresponding examples of benign mimics Synovial sarcoma is frequently misdiagnosed as a benign condition because of its often small size, slow growth, and well-defined appearance. This malignancy is driven by a translocation between.. Ossifying synovial sarcomas have characteristic spotty radio-opacities caused by focal calcifications (Pathol Res Pract 2009;205:195 Synovial sarcoma is often first noticed as a painless lump. If it is near a nerve, it might cause pain or numbness as it grows. Imaging: If you have symptoms of synovial sarcoma, your doctor will use scans such as X-ray, ultrasound, CT scan, and MRI to take pictures of the tumor

Synovial sarcoma of the head and neck region seems to carry a better prognosis than synovial sar-coma of the extremities, with 5-year survival rates ranging from 47% to 82% (7, 8). The CT and MR imaging appearance of synovial sarcomas of the head and the neck has been de-scribed in previous publications as most often wel Synovial Sarcoma. Frontal radiograph of the foot demonstrates a heavily calcified lesion which is arising from the dorsum of the foot between the 2nd and 3rd metatarsals (white arrows).. For this same photo without arrows, click her Synovial sarcoma is a mesenchymal spindle-cell tumor characterized by variable epithelial differentiation. Its chest wall localization represents a diagnostic challenge because of the diverse array of competing diagnosis and rarity of incidence Both biphasic and monophasic synovial sarcomas are usually intermediate grade (grade 2/3); however, both types can be high grade (grade 3/3). 3 Poorly differentiated synovial sarcomas are high-grade tumors. Though plain radiographs and CT may aid in the diagnosis, MRI is the imaging modality of choice for evaluating soft-tissue sarcomas

Imaging of Synovial Sarcoma with Radiologic-Pathologic

Synovial sarcoma is usually slow-growing, so it can be years before a definitive diagnosis is made. In some cases, synovial sarcoma initially is diagnosed incorrectly as arthritis or bursitis. Imaging methods that may be helpful include: Plain X-ray. In some cases, large areas of the tumor are marked or even outlined by calcifications Synovial sarcoma is a high grade, relatively rare neoplasm with an incidence of 2.57 per 100,000 population annually. In contrast to other soft tissue sarcomas, it has a tendency to arise in the extremities of young adults, between the ages of 15 and 40 years. 19 There is a marked predilection for the lower extremity Abstract Synovial sarcoma is a well-recognized soft tissue malignancy that typically arises in young adults. It is now generally accepted that its origin is likely from undifferentiated mesenchymal tissue with variable epithelial differentiation and a highly specific chromosomal translocation in more than 95% of cases Objectives: Synovial sarcomas commonly involve extremities. The purpose of this study was to systematically assess and describe the appearance of pathologically proven synovial sarcomas on conventional MR sequences, diffusion weighted imaging and dynamic contrast enhanced imaging

The above imaging findings are consistent with previous reports.8, 9 To the authors' knowledge, there were no reports concerning the multiphase CT imaging findings of pleuropulmonary synovial sarcoma. In the present series, the tumour showed no prolonged or delayed enhancement in the three cases that underwent multiphase imaging, which was an. Synovial sarcoma: MR imaging findings in 34 patients.

Synovial sarcoma is one of the common malignant mesenchymal tumors, which usually occurs in the extremities of young adults [1, 2, 3].The radiological features of synovial sarcoma, including cyst formation, have been relatively well described [].However, there is limited information on the correlation with the clinicopathologic features [5, 6].We therefore report the radiological and. Synovial sarcoma is a rare cancer that is more commonly diagnosed in people under 40. It is a form of soft tissue sarcoma. Synovial sarcoma usually occurs in the arms and legs, but it can be diagnosed in all parts of the body and in people of all ages. Doctors use imaging to detect synovial sarcoma.

AP (A) and lateral (B) radiographs of the right (R) knee and lower leg in a 31-year-old male demonstrate coarse calcifications within the soft tissues adjacent to the posteromedial tibial plateau, corresponding to a biopsy proven synovial sarcoma We evaluated magnetic resonance imaging (MRI) findings of synovial sarcomas in 22 patients, and the most common MRI findings were oval and well-defined nodular masses with heterogeneous intermediate signal intensity (SI) on T1 weighted images (WI), high SI on T2-WI and heterogeneous contrast enhancement Synovial sarcoma in the proximal forearm shows radiographically visible calcification ( left ).This is found in up to 30% of these tumors. Extrinsic bone erosion of the second metatarsal and cortical thickening of the third metatarsal is seen in this foot tumor ( right ).Periosteal reaction is seen in 11% to 20% of synovial sarcomas, and cortical erosion in 5% Objectives. Synovial sarcomas commonly involve extremities. The purpose of this study was to systematically assess and describe the appearance of pathologically proven synovial sarcomas on conventional MR sequences, diffusion weighted imaging and dynamic contrast enhanced imaging Synovial sarcoma. Synovial sarcoma is the fourth most common soft tissue sarcoma, 18-25% of which occur in the ankle and foot making it the most common malignancy in this region [14,15,16, 31]. Despite its name, it is in fact a lesion of mesenchymal origin and is named for its histological resemblance to synovial tissue [16, 31]

The purpose of this study is to evaluate the safety and effectiveness of AL3818 (catequentibub, anlotinib) hydrochloride in the treatment of metastatic or advanced alveolar soft part sarcoma (ASPS), leiomyosarcoma (LMS), and synovial sarcoma (SS). All participants with ASPS will receive open-label AL3818 Synovial sarcoma (SS) is a rare malignant neoplasm that arises most commonly in joint capsules and articular tendons, but its relationship to the synovium is not always obvious. Synovial sarcoma is a malignant soft tissue tumor representing 5.6% to 10% of all soft tissue sarcomas. They are termed SS because of their histologic resemblance to the synovium, but they rarely involve a synovial. Abstract: Soft tissue sarcoma of the hand is rare, with synovial sarcoma being among the most common pathological diagnoses. As postoperative radiation therapy for synovial sarcoma, a 22-year-old male patient was treated with a total dose of 60 Gy, administered in 30 daily fractions

Synovial sarcoma is a common soft tissue malignancy accounting for 5 - 10 % of soft tissue sarcomas. Patients with synovial cell sarcoma are often between the ages of 15 and 35 years old; generally younger than patients with other types of soft tissue sarcomas. The most probable cellular origin is an undifferentiated mesenchymal cell We studied the MR features of synovial sarcoma in 34 patients to determine if these tumors have specific MR findings that can be used to suggest the diagnosis. MATERIALS AND METHODS: MR imaging studies of 34 patients with synovial sarcoma were collected from two institutions and studied to determine the following characteristics of the tumor. Synovial sarcomas (SS) represent a unique subset of soft tissue sarcomas (STS) and account for 5-10% of all STS. Synovial sarcoma differs from other STS by the relatively young age at diagnosis and clinical presentation. Synovial sarcomas have unique genomic characteristics and are driven by a pathognomonic t(X;18) chromosomal translocation and subsequent formation of the SS18:SSX fusion. Synovial sarcoma mostly affects the limbs, and in order for the surgeon to achieve these margins in this area of the body some patients will receive limb-sparing surgery. This is where the affected bone is taken out and then replaced with a specially designed metal replacement (prosthesis) or bone graft (bone taken from another part of the body)

We report on a 23-year-old woman with a poorly differentiated synovial sarcoma on the palm of her hand which presented as a painless nodule. The MRI findings are presented along with the clinical and pathologic features. Becaue of similar morphological features, these tumors can be confused with benign lesions such as aggressive fibromatosis or ganglion cysts, especially when very small. The. CT scan will detect the location of the tumor and will show the local invasion or distant metastasis. Magnetic resonance imaging is considered a better imaging tool than a CT scan, as it provides higher resolution and can detect invasion of the myocardium . Very few cases of synovial sarcoma have been reported in the past Primary synovial sarcomas are most common in the soft tissue near the large joints of the arm and leg, but has been found in most human tissues and organs, including the brain, prostate, and heart. Synovial sarcoma occurs most commonly in the younger patients under 30 years of age. While overall comprising about 8% of all soft tissue sarcomas.

1 Introduction. Synovial sarcoma (SS) is a rare type of cancer, which occurs in 5% to 10% of soft tissues. It tends to arise the most frequently in the lower limbs of the body. However, tumors may develop in other parts of the body, that is, head, neck, trunk, and pelvis. Primary renal synovial sarcoma (PRSS) is rarer compared with SS.. SS typically occurs in young adults and has a poor. Diagnosis and Radiology. Synovial sarcoma may be diagnosed through various imaging studies like radiographic examination, ultrasound, computed tomography (CT scan) and magnetic resonance imaging (MRI). These imaging studies would be helpful in determining the size and location of the tumor Synovial sarcoma (SS) is a rare type of cancer. It affects soft tissues, which connect, support, and surround bones and organs in your body. These may include muscle, fat, blood or lymph vessels.

However, only few studies have been reported on intraosseous synovial sarcoma, and reports on cases with cytogenetic or molecular confirmation are even. Importance Synovial cell sarcoma of the head and neck (SCSHN) is a rare tumor associated with significant morbidity and mortality. The literature regarding these tumors is limited to case series and case reports. We used data from the population-based US Surveillance, Epidemiology, and End Results (SEER) cancer registry to determine factors affecting both overall survival and disease-specific.

Synovial Sarcoma. - See: Soft Tissue Tumor Menu. - Discussion: - 4th most common soft-tissue sarcoma (5 to 10 percent of all cases of soft-tissue sarcoma) - tumor derived from the synovial tissues found along fascial planes, periarticular structures, and rarely, in joints; - it may involve the sheaths and bursae of the tendons; - presentation MRI (magnetic resonance imaging) MRI uses radio waves and strong magnets instead of x-rays to take pictures of the body. MRI scans are often part of the work-up of any tumor that could be a sarcoma. They're often better than CT scans in evaluating sarcomas in the arms or legs. MRI provides a good picture of the extent of the tumor The novel SS18-SSX fusion-specific antibody is reported to have high sensitivity and specificity for the diagnosis of primary synovial sarcoma (SS), which often metastasizes to the lung. Thus far, no study has validated the diagnostic efficacy of SS18-SSX antibody for pulmonary metastatic SS. Therefore, we aimed to investigate the usefulness of the SS18-SSX antibody in the diagnosis of. Malignant tumors include synovial sarcoma and soft tissue sarcoma.

Catequentinib is effective for the treatment of patients with synovial sarcoma, said Van Tine in concluding his presentation at the American Society of Clinical Oncology (ASCO) virtual meeting. This finding is further supported an additional study of 1,240 patients from the French Federation of Cancer Centers Sarcoma Group which found that histologic grade was prognostic in MFH, unclassified sarcomas, synovial sarcomas, LMS, and LPS, but not in other STS subtypes . Thus, using histologic grade as the primary variable to craft. Diagnosis of the synovial sarcoma involves imaging of the affected area, biopsy, genetic testing, and bone scans. Treatment of the synovial sarcoma involves a few approaches ranging from. Afami-cel is a specific peptide enhanced affinity receptor (SPEAR) T-cell therapy that is engineered to target MAGE-A4 peptide expressed on tumor cells. In the context of HLA-A*02, MAGE-A4 is highly expressed in synovial sarcoma and MRCLS. 2 The T-cell therapy previously demonstrated clinical activity in in various tumors in a phase 1 study.
