11/15. Multifocal pyomyositis. diagnosis on technetium-99m MDP bone scan.pyomyositis is a bacterial infection of skeletal muscle occurring in the absence of trauma or a primary site of infection. The condition is rare in temperate climates. The diagnosis is often difficult to make and frequently delayed since the suppurative process is confined by the tense overlying muscle and fascia. The bone scan is very useful in differentiating underlying osteomyelitis and septic arthritis. An 11-year-old boy is described who presented with multifocal pyomyositis in the elbow region and thigh. Lateral blood pool images suggested infection with liquefaction within the muscles without evidence of osteomyelitis.- - - - - - - - - - ranking = 1keywords = bacterial infection (Clic here for more details about this article) |
12/15. pyomyositis in a neonate.pyomyositis, better known as tropical pyomyositis in other areas of the world, is a relatively rare condition in temperate climates such as the united states. The disease is a bacterial infection of muscle with abscess formation usually caused by staphylococcus aureus. skin findings are rare until late in the course of the disease. We present a 3-week-old male infant in whom skin findings were an early presentation. This is the first known case of pyomyositis in a neonate in the united states and the only known case of pyomyositis reported in the dermatologic literature. A high index of suspicion is needed, because considerable delay in accurate diagnosis can occur.- - - - - - - - - - ranking = 1keywords = bacterial infection (Clic here for more details about this article) |
13/15. bacteroides fragilis pyomyositis in a patient with multiple myeloma.pyomyositis is a bacterial infection with abscess formation affecting large skeletal muscles. It is predominantly caused by staphylococcus aureus. The disease is common in tropical areas, but rare in temperate climates. We report a patient with multiple myeloma who developed a giant elastic tumor on the right thigh and a hen egg-sized tumor on the right upper arm. MR imaging revealed cystic spaces in the femoral quadriceps and brachial biceps muscles. A large amount of pus with foul smell was removed by incision, drainage and aspiration of the two tumors. The lesions were successfully treated with intravenous administration of antibiotics. Repeated bacterial cultures yielded only Bacteroids fragilis. To our knowledge, this is the first report of pyomyositis due to bacteroides fragilis.- - - - - - - - - - ranking = 1keywords = bacterial infection (Clic here for more details about this article) |
14/15. Iliacus pyomyositis mimicking septic arthritis of the hip joint.The iliacus muscle is closely associated with the psoas muscle, femoral nerve, hip joint, pelvic and intraabdominal structures; thus, its disorders may present as lower abdominal pain, hip pain, or femoral neuropathy. Iliacus pyomyositis, a primary bacterial infection of the skeletal muscle not secondary to a contiguous skin, bone, or soft-tissue infection, presenting as hip pain, femoral neuropathy, and sympathetic effusion of the hip joint in an 8-year-old boy mimicked septic arthritis of the hip joint. Computed tomography was helpful in delineating the accurate location of the lesion. Surgical drainage and appropriate antibiotic therapy led to complete resolution and full functional recovery.- - - - - - - - - - ranking = 1keywords = bacterial infection (Clic here for more details about this article) |
15/15. A case of streptococcal myositis (misdiagnosed as hamstring injury).Streptococcal myositis is a very rare bacterial infection of muscle with a high mortality. diagnosis is difficult because of the paucity of clinical signs and symptoms at the onset. However, presentation of the disease appears to have changed over the last 50 years. A case of streptococcal myositis is presented (misdiagnosed as hamstring injury), which more closely reflects the current presentation of the disease. Some of the features that may help emergency clinicians to recognise the onset of the condition are highlighted.- - - - - - - - - - ranking = 1keywords = bacterial infection (Clic here for more details about this article) |
