1/43. 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) |
2/43. pyomyositis in a 5-year-old child.We present a case of pyomyositis in an otherwise healthy 5-year-old child that underscores the potential for serious, life-threatening complications. pyomyositis of the gluteal, psoas, and iliacus muscles was associated with osteomyelitis, septic arthritis, a large inferior vena cava thrombus, septic pulmonary emboli, and eventual pneumonia. Primary pyomyositis is a purulent infection of striated muscle thought to be caused by seeding from a transient bacteremia. The focal infection typically forms an abscess that generally responds to intravenous antibiotics and occasionally requires adjunctive computed tomography-guided aspiration and drainage. This localized infectious process rarely produces further sequelae unless treatment is delayed. pyomyositis is rare in healthy individuals and requires a high clinical suspicion in patients who present with fever, leukocytosis, and localized pain.- - - - - - - - - - ranking = 0.4keywords = pyomyositis (Clic here for more details about this article) |
3/43. Obturator internus muscle abscess in children.The authors describe four cases of obturator internus muscle (OIM) abscess in children, including their clinical presentations and treatment. This was a retrospective chart review. Children and adolescents younger than 18 years discharged between July 1, 1985, and September 30, 1998, from Brenner Children's Hospital with the diagnosis of muscle abscess or pelvic abscess were identified. A total of 56 patients were identified with the diagnosis of muscle abscess or pelvic abscess. OIM abscess was defined by radiologic findings of an inflammatory process with fluid collection in the OIM, along with the clinical findings suggestive of an OIM abscess. Four of the patients met the definition of OIM muscle abscess. The common presenting features were fever, limp, and hip pain. Computed tomography or magnetic resonance imaging was diagnostic in all four patients, and staphylococcus aureus was the causative agent in each. All the patients recovered, one after surgical drainage and the other three after antimicrobial therapy alone or with needle aspiration. The presentation of OIM pyomyositis is similar to that of psoas muscle pyomyositis and other infectious processes of the pelvis and hip. The S. aureus is the most common etiologic agent but not the only one reported. Most patients can be managed without open surgical drainage, but needle aspirations may be helpful both therapeutically and diagnostically.- - - - - - - - - - ranking = 0.4keywords = pyomyositis (Clic here for more details about this article) |
4/43. 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) |
5/43. Type 2 diabetes complicated by multiple pyomyositis.A 40-year-old man was hospitalized due to fever, muscular swelling and pain. He had poorly controlled diabetes with many dental caries and repeated periodontitis. CT revealed multiple intramuscular abscesses; administration of antibiotics and pus drainage were performed. Intraoral infection was suspected as the route of infection of pyomyositis, and a total of six teeth was extracted. In the clinical treatment of diabetic patients, it is important to instruct patients to routinely check for the presence of traumatic injuries of the lower extremities, and to have routine check-ups and dental care to check for dental caries or periodontitis.- - - - - - - - - - ranking = 1keywords = pyomyositis (Clic here for more details about this article) |
6/43. A case confirming the progressive stages of pyomyositis.A teenage boy presented in the early stage of pyomyositis. He had neck pain, tenderness, and fever. A computed tomography scan showed inflammation in the sternocleidomastoid muscle with no fluid collection. This progressed to a pus-filled drainable mass caused by Stapylococcus aureus. The authors describe this case to highlight the predictable stages and increase the index of suspicion to enhance its early recognition.- - - - - - - - - - ranking = 1keywords = pyomyositis (Clic here for more details about this article) |
7/43. Piriformis pyomyositis: a rare cause of sciatica.A 30-year-old Thai woman with piriformis pyomyositis presented with sciatica. Computed tomography showed swelling and enhancement of the right gluteus medius and piriformis muscles. She made a complete recovery after a course of intravenous antibiotics. This condition has only been reported three other times and is often diagnosed with difficulty. It could be erroneously dismissed as a lumbar disc prolapse. If untreated, it could lead to prolonged hospital stay and death. A high index of suspicion, early diagnosis and appropriate antibiotic or surgical treatment leads to full recovery.- - - - - - - - - - ranking = 1keywords = pyomyositis (Clic here for more details about this article) |
8/43. Tropical pyomyositis.Although rare, tropical pyomyositis can result from staphylococcal bacteremia and should be considered in the different diagnosis of fever associated with extremity pain. The diagnosis is readily made with a CT scan. Treatment is primarily medical with surgery reserved for refractory abscesses.- - - - - - - - - - ranking = 1keywords = pyomyositis (Clic here for more details about this article) |
9/43. Multifocal pyomyositis in an immunocompetent patient.pyomyositis is defined as suppurative infection of the skeletal muscle and usually occurs in immunocompromized patients. We managed a 23-year-old man admitted for myalgia and evidence of infection, with onset after a strenuous physical activity. Numerous muscles were involved. Multiple abscesses were visualized by ultrasonography and computed tomography, with predominant involvement of the pelvic muscles. Examination of the aspirate from a forearm abscess recovered staphylococcus aureus. No factors associated with immunodeficiency were found. Appropriate antimicrobial therapy ensured complete resolution of the infection. pyomyositis is rare in immunocompetent individuals. myalgia, fever, and rhabdomyolysis should suggest pyomyositis. Computed tomography and magnetic resonance imaging are the best investigations for confirming the diagnosis.- - - - - - - - - - ranking = 1keywords = pyomyositis (Clic here for more details about this article) |
10/43. An unusual presentation of tropical pyomyositis.Tropical pyomyositis is a primary pyogenic infection of skeletal muscle, often caused by staphylococcus aureus. The most common presentation of tropical pyomyositis is that of multiple acute abscesses with fever. hepatitis is a rare manifestation of this disease. We report a case of tropical pyomyositis who presented with hepatic encephalopathy leading to initial diagnostic dilemma.- - - - - - - - - - ranking = 1.4keywords = pyomyositis (Clic here for more details about this article) |
