  An enlarging soft tissue mass may be mistaken for a solid tumor, such as a sarcoma. When fever accompanies focal pain, possible osteomyelitis or septic arthritis is often considered. [oncologynurseadvisor.com]

• Agalactia

  Upon a blood culture, Streptococcus agalactiae was identified, confirming Group B streptococcal myositis, and in Figure 5, an MRI of the rectus muscle can be seen. Figure 5. [microbewiki.kenyon.edu]

After all the initial workups and serology were negative, imaging was considered. [mdpi.com]

The inherited disorders are rare and should be considered only if the inpatient workup does not reveal an obvious cause or if the pattern of illness is highly suggestive of an inherited disorder. [clinicaladvisor.com]

Reports indicated that immunocompromised patients should be treated by broad-spectrum antibiotics, for targeting a wide-range of gram-negative and anaerobic pathogens [29] However, Immune workup was not studied in our patient, due to the lack of evidence [medcraveonline.com]

According to Monto et al ., the positive predictive value of typical viral symptoms (as demonstrated in all of our cases) during an influenza epidemic is about 80%. [27] Muscle biopsy is not routinely recommended in the workup of viral myositis as a negative [ruralneuropractice.com]

Treatment of pyomyositis is usually in relation to the stage of the disease at the time of the diagnosis. In the early invasive stage, empirically administered antibiotics are considered the treatment of choice [26]. [medcraveonline.com]

Treatment and prognosis Depending on the infective agent systemic antibiotics are administered. If an abscess has formed, then it should usually be drained either surgically or percutaneously. [radiopaedia.org]

If a person with dermatomyositis develops cancer, the prognosis may be worse. Medications taken to treat these muscle diseases may cause complications that affect prognosis. [drugs.com]

Concurrent neutropenia, regardless of cause, predisposes to C. septicum bacteremia, which results in a poor prognosis; the prognosis is worse if intravascular hemolysis occurs. [merckmanuals.com]

In most cases, the prognosis following satisfactory drainage is excellent, with little long-term morbidity. [oncologynurseadvisor.com]

Bacterial etiologies did not differ significantly between cases of myositis or pyomyositis. [mdedge.com]

Conclusions Acute symmetrical proximal muscle weakness has varied etiologies. [mdpi.com]

The diagnosis of myositis is suggested by the clinical picture and radiologic imaging, and the etiologic agent is confirmed by microbiologic or serologic testing. Therapy is based on the clinical presentation and the underlying pathogen. [scinapse.io]

The spectrum of acute myopathy includes various etiologies with different pathophysiology. [annalsofian.org]
