1/88. polymyositis with biological false-positive serological test for syphilis. A case report.A young female came to the clinic with polymyositis and a biological false-positive serological test for syphilis (BFP reaction). polymyositis, like other connective-tissue diseases, should be considered in the study of BFP reactors.- - - - - - - - - - ranking = 1keywords = connective (Clic here for more details about this article) |
2/88. MRI of tuberculous pyomyositis.PURPOSE: The purpose of this article is to describe the findings of MRI in tuberculous pyomyositis (PM). METHOD: The MR images of four proven cases of tuberculous PM were retrospectively reviewed and analyzed with clinical and laboratory findings. The location, signal intensity on T1- and T2-weighted spin echo images, presence of abscess, signal intensity of peripheral rim, patterns of contrast enhancement, and associated findings were evaluated. RESULTS: On MR images, all cases demonstrated low signal intensity on T1-weighted images and high signal intensity on T2-weighted images in a single muscle. abscess was seen in all cases. Peripheral rim showed subtle hyperintensity on T1-weighted images and hypointensity on T2-weighted images. After gadolinium infusion, peripheral rim enhancement was observed in all cases. cellulitis was associated in one case. The patients clinically presented with a palpable mass of long duration. CONCLUSION: Tuberculous PM shows characteristic findings of a well demarcated abscess with rim enhancement at MRI and can be distinguished from other soft tissue masses.- - - - - - - - - - ranking = 0.021746881517544keywords = soft (Clic here for more details about this article) |
3/88. Focal myositis presenting with radial nerve palsy.Focal myositis is a rare inflammatory pseudotumor of skeletal muscle which usually has a benign course. We report a 56-year-old woman with a painful mass in the left arm with a radial nerve palsy. magnetic resonance imaging (MRI) of the left arm showed a mass in the triceps muscle that was suggestive of a soft-tissue sarcoma. electromyography showed a severe radial neuropathy involving both motor and sensory axons. An open biopsy showed focal myositis. Treatment with corticosteroids resulted in complete disappearance of the mass clinically and by MRI, without recurrence for more than 2 years. radial nerve function also recovered completely. As a treatable cause of focal neuropathy, focal myositis should be included in the differential diagnosis of a muscle mass.- - - - - - - - - - ranking = 0.021746881517544keywords = soft (Clic here for more details about this article) |
4/88. Nodular sarcoid myositis of skeletal muscle diagnosed by fine needle aspiration biopsy. A case report.BACKGROUND: Symptomatic striated muscle involvement in sarcoidosis is rare. Muscle biopsy is usually required for the diagnosis. Fine needle aspiration biopsy (FNAB) has been successfully used in diagnosing soft tissue lesions. To the best of our knowledge, FNAB of sarcoid myositis has not been reported. CASE: A 31-year-old, black female with a history of sarcoidosis presented with an enlarging, painful, left calf mass. Infected thrombi were suspected. FNAB showed numerous loosely arranged epithelioid histiocytes, multinucleated giant cells and skeletal muscle cells. The overall cytologic picture was that of granulomatous myositis. The cytologic features coupled with the patient's history and magnetic resonance imaging findings suggested sarcoid myositis. Subsequent muscle biopsy showing noncaseating granulomata and negative stains for organisms confirmed the diagnosis of nodular sarcoid myositis. CONCLUSION: Nodular sarcoid myositis can be suggested by FNAB cytology in a patient with a past history of sarcoidosis.- - - - - - - - - - ranking = 0.021746881517544keywords = soft (Clic here for more details about this article) |
5/88. mixed connective tissue disease.Three patients with mixed connective tissue disease (MCTD) had clinical features that included a high incidence of Raynaud phenomenon, arthritis, myositis, and swollen hands. The diagnostic laboratory test result was the presence of high titers of antibody to extractable nuclear antigen. These antibody titers are notably reduced or abolished in patients with MCTD when the tanned red blood cells that are used in the test are pretreated with ribonuclease. Speckled antinuclear antibodies were present in all patients. patients with MCTD have a low incidence of renal disease, are responsive to treatment with prednisone, and have a good prognosis.- - - - - - - - - - ranking = 5keywords = connective (Clic here for more details about this article) |
6/88. Clinical, pathological and magnetic resonance imaging features of focal myositis: report of three cases.Focal myositis is a rare idiopathic form of inflammatory myositis involving a single muscle. The presentation is often as a soft tissue pseudotumour. Magnetic resonance imaging (MRI) is a useful noninvasive imaging modality to demonstrate focal nature of the lesion. We describe three patients presenting as pseudotumour of the lower leg. MRI showed hyperintense signals in the involved muscle.- - - - - - - - - - ranking = 0.021746881517544keywords = soft (Clic here for more details about this article) |
7/88. Fine-needle aspiration findings in nodular myositis: a case report.Fine-needle aspiration (FNA) is frequently the initial diagnostic modality for the workup of suspected metastatic disease in subcutaneous or deeper soft tissues. The technique is less well-accepted for the diagnosis of primary soft-tissue lesions. Occasionally during the investigation of suspected metastatic disease, primary processes of the soft tissues will undergo FNA. Thus, familiarity with the cytomorphology of soft-tissue reparative and neoplastic lesions is important. A variety of reparative and degenerative entities exist within the soft tissues, one of which is localized nodular myositis. This lesion may be a precursor of generalized polymyositis, including polymyositis associated with graft vs. host disease, or it may remain a localized process. Aspirates from localized nodular myositis demonstrate fragments of striated muscle including degenerating and regenerative myocytes, a mixed inflammatory background, and necrotic debris. Cytologic identification of this lesion can be therapeutically important, particularly in post-bone marrow transplant patients.- - - - - - - - - - ranking = 0.10873440758772keywords = soft (Clic here for more details about this article) |
8/88. Glycogenosis type V (McArdle's disease) mimicking atypical myositis.A 13-year-old girl was referred to our clinic because of a positive rheumatoid factor test, muscle pain and weakness. Laboratory evaluation revealed an increased ESR, hypergammaglobulinaemia, antinuclear antibodies, circulating immune complexes, complement consumption and elevated serum creatine kinase (CK) activity. A needle biopsy of the dolent muscle showed normal routine histology. immunohistochemistry disclosed single lymphocytes and a weak myocytic HLA class I expression. The diagnosis of myositis was considered and corticosteroids were initiated, leading to an increase of complement levels and a decrease of CK-activity and ESR. She subjectively felt stronger but still reported exercise intolerance and metabolic myopathy was considered. Myophosphorylase activity was completely lacking, establishing the diagnosis of McArdle's disease. CK level was found to be elevated in an obese 4-year-old brother too, who refused extensive walking but reported no muscle pain. Myophosphorylase deficiency was demonstrated by histochemistry and by biochemical analysis of his muscle. The female case illustrates that in children with the clinical picture of inflammatory myopathy and serological but not clinical response to therapy underlying metabolic muscle disorders should be excluded. Since the pathogenesis of polymyositis remains unclear, we speculate that inflammatory changes observed in the muscles may have been initiated by muscular damage resulting from the underlying metabolic disease. The serological changes remained unexplained and may contribute to a so far undeterminable connective tissue disease.- - - - - - - - - - ranking = 1keywords = connective (Clic here for more details about this article) |
9/88. Effect of myocutaneous inflammatory changes caused by intra-arterial chemotherapy on the outcome of patients who undergo limb-saving surgery.BACKGROUND: This study examined the effect of myocutaneous inflammatory changes caused by intra-arterial chemotherapy on the outcome of patients who undergo limb-saving surgery. methods: One hundred seven patients with malignant bone and soft tissue tumors were administered intra-arterial cisplatin and caffeine preoperatively with or without doxorubicin. Nine patients (8.4%) who had had myocutaneous inflammatory reactions were reviewed to determine the effects of this complication on limb-saving surgery. RESULTS: The patients complained of unbearable and continuous pain while undergoing intra-arterial infusion. gait disturbances and muscle weakness were caused by their severe regional pain, resulting in the use of crutches even before surgery. Extended areas of necrotic skin and muscle were resected simultaneously with limb-saving surgery on four patients. Myocutaneous necrosis in one patient, indurations in two patients, and flares in two patients were not treated surgically. pain relief was provided to eight patients at some point. Four patients with extensive myocutaneous necrosis around the knee joint had restricted range of motion and poor functional results. radionuclide angiography using 99m-technetium-macroaggregated albumins was performed to evaluate the blood flow to the affected muscle and tumor. It showed marked increase of the radioisotope perfusion in the affected muscles but little uptake in the tumor. These results may suggest that the affected muscles diminish the effects of anticancer drugs on the tumors. CONCLUSIONS: Myocutaneous inflammatory reactions should be prevented if possible to obtain good limb function and chemotherapeutic effects in patients who undergo intra-arterial chemotherapy. Resection of necrotic tissue is mandatory to relieve pain.- - - - - - - - - - ranking = 0.021746881517544keywords = soft (Clic here for more details about this article) |
10/88. Inflammatory myositis: a rare differential diagnosis of a neck lump.Inflammatory myositis is an extremely rare benign inflammatory condition of skeletal muscle. It usually affects the extremities, and there are only 10 cases reported in the head and neck region. Its significance is that in this region it can be clinically mistaken for a neoplasm. We describe a case and review the literature.- - - - - - - - - - ranking = 0.0089576197017921keywords = neoplasm (Clic here for more details about this article) |
