1/6. 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 = 1keywords = pyomyositis (Clic here for more details about this article) |
2/6. Primary tuberculosis in the gluteal muscle of a patient with chronic renal failure. A rare presentation.patients suffering from chronic renal failure (CRF) are at increased risk for contracting tuberculosis (TB) due to their impaired immunity. In this patient group, extrapulmonary involvement is more common than the pulmonary form of TB, and symptoms tend to be milder and less distinctive than those seen in the general population. pyomyositis secondary to TB is relatively rare. We report a case of TB pyomyositis in the setting of CRF. The nonspecific symptoms that are typical of CRF patients with TB make it particularly difficult to establish the diagnosis in this patient group. In order to avoid diagnostic delays, which may increase the risk of complications and mortality, TB should be kept in mind in any case of ongoing fever and infection that does not respond to seemingly appropriate therapy. In addition, TB should always be suspected in endemic areas, even in the absence of osseous involvement.- - - - - - - - - - ranking = 0.2keywords = pyomyositis (Clic here for more details about this article) |
3/6. Tuberculous pyomyositis.Tuberculosis, caused by mycobacterium tuberculosis is a common infection both in immunocompromised and normal hosts. Its clinical manifestation can by divided as pulmonary and extrapulmonary form. pyomyositis caused by M. tuberculosis is extremely rare. The authors report 2 patients, one with underlying dermatomyositis, and the other with polymyositis. The diagnosis was delayed according to nonspecific symptoms and masking effect of steroid therapy, which led to complications. microscopy and culture of the pus confirmed the diagnosis. Surgical drainage was done and antituberculous therapy was given. The patient with dermatomyositis was complicated by drug induced hepatitis and died but the other was cured. Tuberculous pyomyositis should be considered in patients who are immunocompromised hosts.- - - - - - - - - - ranking = 1keywords = pyomyositis (Clic here for more details about this article) |
4/6. Tuberculous pyomyositis in a renal transplant recipient.Infections are a major cause of morbidity and mortality in renal transplant recipients. Although these patients are susceptible to many types of infection, soft tissue infections are rare. We report a case of tuberculous pyomyositis involving the left erector spinae muscle but with no other manifestations of tuberculosis. The diagnosis was suspected from the CT scan appearance and confirmed by microscopy and culture of the pus. Surgical incision and drainage, together with antituberculosis therapy, cured the infection. The relevant literature is briefly reviewed.- - - - - - - - - - ranking = 1keywords = pyomyositis (Clic here for more details about this article) |
5/6. Tuberculous pyomyositis of the temporal muscle in a nonimmunocompromised woman: diagnosis by sonography.pyomyositis (PM) is an uncommon cause of acute bacterial infection occurring in skeletal muscle. This disease is rare in non-tropical areas, and PM caused by Mycobacterium is very rare in a non-immunocompromised person. The presence of temporal area swelling may lead to a differential diagnosis toward more common pathologies, such as a complication of mastoiditis or a neoplasm of the temporal area. This article describes a case of tuberculous pyomyositis in a non-immunocompromised woman, the diagnosis of which was confirmed by sonographically guided fine-needle aspiration.- - - - - - - - - - ranking = 1keywords = pyomyositis (Clic here for more details about this article) |
6/6. Tuberculous skeletal muscle involvement in acute leukemia: report on two cases.Bacterial infection of skeletal muscle (pyomyositis) is usually followed by abscess formation. The most commonly isolated pathogen is staphylococcus aureus. Tuberculosis rarely affects patients with acute leukemia. The authors report on 2 patients, one with acute myelogenous leukemia and the other with acute lymphoblastic leukemia whose clinical course was complicated by tuberculous skeletal muscle abscesses. In both instances, musculoskeletal pain was accompanied by evidence of muscle abscesses by imaging studies of the painful areas. Therefore, in patients with acute leukemia and evidence of muscle abscesses with initial cultures negative for bacteria and fungi, one should include tuberculosis in the differential diagnosis.- - - - - - - - - - ranking = 0.2keywords = pyomyositis (Clic here for more details about this article) |
