The lacrimal glands, salivary glands and pancreas are typically affected. We report a case of IgG4-related disease presenting a soft tissue tumor affecting skeletal muscle. Case Report: A 32-year-old man presented a soft tissue mass in his left arm. Magnetic resonance imaging revealed a spindle like, peripheral mass, in the lateral head of the triceps of his left arm. Tru-Cut Biopsy provided the diagnosis of IgG4-related disease affecting skeletal muscle. Glucocorticoid treatment was effective. Conclusion: To our knowledge, this is the first reported case of IgG4-related disease affecting skeletal muscle and presenting a soft tissue mass.展开更多

Sonography revealed bone destruction in all 48 cases, elevated periosteum in 26 cases and soft tissue mass in 34 cases. The results obtained in this series demonstrate that mostbone tumors have their characteristic sonographic features such as giant cell tu-mors, malignant bone tumors, bone cysts, as well as metastatic lesions. Studyshowed that sonography has equally high accuracy in the diagnosis of these tumorscompared with radiography.展开更多

A comparative study was performed on 45 cases of osteosarcomas by ultrasonography and radiography. Bony changes, periosteal reaction and soft tissue mass were evaluated for each lesion. The results showed that ultrasonography revealed a solid mass around bone in 42 patients, bone destruction in 24 patients and periosteal reaction in 16 patients. Plain radiographs showed bony changes in 44 patients and no bony change in remaining one patient, shadowing of soft tissue swelling in 30 patients, and pulmonary metastases in 3 patients. Surgical biopsy and pathological examination confirmed osteosarcoma in all 45 patients. Soft tissue mass was confirmed in 42 patients surgically. The diagnostic accuracy of soft tissue masses by ultrasonography and radiography was 100 % （42/42） and 71.4 % （30/42）, respectively. The positive rate of ultrasonography and radiography in displaying bony changes was 53.3 % （24/45） and 97,8 % （44/45）, respectively. In conclusion, in the detection of soft tissue mass of osteosarcoma, ultrasonography is superior to radiography, and in displaying bony changes of osteosarcomas, radiography is superior to ultrasonography. So it may come to a conclusion that plain radiography combined with ultrasonography can completely display the bony and soft tissue lesion of osteosarcomas.展开更多
