Streptococcal Pyomyositis of the Psoas

We present two unusual cases of pyomyositis of the psoas muscle caused by Group A beta-hemolytic streptococcus (GABHS) in children presenting with fever, emesis and leg pain. Pyomyositis secondary to GABHS is rare in children and cases involving the psoas muscle have not been previously reported. In our discussion, we review the epidemiology, presentation, diagnosis and treatment of GABHS psoas myositis in comparison with staphylococcal pyomyositis. Prompt recognition of the signs and symptoms of GABHS psoas pyomyositis is essential for treatment of this life-threatening infection.

Multifocal Streptococcal Pyomyositis Complicated by Acute Compartment Syndrome: Case Report

A 5-year-old girl sought treatment for pyrexia of unknown origin. Despite prompt surgical drainage of a streptococcal septic arthritis of the ankle joint, her condition deteriorated. Multifocal pyomyositis was subsequently diagnosed. This was complicated by acute compartment syndrome in three extremities. With aggressive surgical and medical management, the child made a complete recovery. Orthopaedic clinicians in nontropical areas must familiarize themselves with this rare, potentially life-threatening, but eminently curable disease.

A Case of Group B Streptococcal Pyomyositis

The group B streptococcus is an opportunistic pathogen that causes a variety of serious infections including bacteremias, puerperal sepsis, and neonatal meningitis. Group B streptococcal infections of muscle are rare. We report here an unusual case of group B streptococcal pyomyositis. Pyomyositis arises predominantly from infections caused by Staphylococcus aureus and, occasionally, Streptococcus pyogenes. Because of the rarity of pyomyositis in temperate climates, the common lack of localizing signs or symptoms, and the frequently negative blood cultures, considerable delay often precedes the diagnosis of pyomyositis; in fact, the infection has been initially misdiagnosed as muscle hematoma, cellulitis, thrombophlebitis, osteomyelitis, or neoplasm. Diagnosis may be greatly aided by radiologic techniques that can demonstrate the sites of muscle enlargement and the presence of fluid collections. The response to antibiotics is usually rapid, but resolution of the infection may require aspiration of deeply situated muscle abscesses. This report describes a diabetic patient with an unusual presentation of pyomyositis that mimicked an acute abdomen.

Pyomyositis in a Patient With Progressive Systemic Sclerosis

Pyomyositis has become an increasingly recognized disease in temperate climates. A patient receiving chlorambucil for progressive systemic sclerosis, in whom streptococcal pyomyositis developed, is presented. Magnetic resonance imaging led to the early diagnosis. To our knowledge, this is the first case report of pyomyositis in a patient with scleroderma, and the first association with group G streptococcus infection in an adult. Connective tissue diseases and immunosuppression may emerge as risk factors for the development of this entity.

Peracute Streptococcal Pyomyositis

Pyomyositis occurs infrequently in temperate climates. The fulminating peracute form caused by group A Streptococcus is exceedingly rare. We present two children with streptococcal pyomyositis. One child was admitted in septic shock and required intensive supportive care during the acute stage of his illness. Persistent swelling and tenderness of his left thigh presented a diagnostic problem, which was eventually resolved with the aid of computerized tomography. Despite appropriate antibiotic therapy from the onset of illness, surgical debridement of the affected muscle was necessary. The second child presented with pyomyositis of the left paravertebral muscles and signs of incipient shock but did well on antibiotic therapy alone.
