Primary Suppurative Myositis in Children

Tropical pyomyositis

“…Tropical pyomyositis is an endemic disease in many parts of Africa, South America, the West Indies, Southeast Asia, and Micronesia (4). Although cases have occasionally been reported in temperate zones (1,4,5,(10)(11)(12)(13)(14), these have often been patients like ours, who had recently immigrated from the tropics or subtropics. Typically, tropical pyomyositis manifests in one of three clinical syndromes or stages, depending on the diagnostic interval (2).…”

Diagnosis of Iliopsoas Pyomyositis by Ultrasonography and CT

“…Harris reported that no treatment, or treatment with antimicrobial therapy alone, is associated with a 100% mortality rate for retroperitoneal abscesses [5] . Although the majority of patients with pyomyositis with require drainage [5,[14][15][16], our case was successfully treated with intravenous antibiotics alone. Early diagnosis of pyomyositis, prior t o suppuration, as identified on CT or US, is thought to be most important in determining if antibiotics alone will be adequate therapy.…”

Pectoralis major muscle abscess in an immunocompromised adult

“…For stage 1, the appropriate treatment is antibiotics that treat the causative organism, as Staphylococcus aureus accounts for 70–95% of the cases, mostly penicillin resistant [ 7 , 17 , 18 ]. Other rare causative organisms include group A beta-hemolytic streptococci, alpha-hemolytic and non-hemolytic streptococci, Staphylococcus epidermidis, Staphylococcus pyogens, Streptococcus pneumonia, Streptococcus pyogens, Haemophilus influenza, Escherichia coli, Neisseria gonorrhea, Klebsiella, Yersinia enterocolitica, Pseudomonas species , Pasteurella species , Salmonella typhi , and tubercle bacilli [17] , [18] , [19] ]. For stages 2 and 3, treatment requires the percutaneous drainage or surgical drainage of the abscesses and antibiotics according to the culture of the purulent material, specifically those covering gram-positive and gram-negative bacteria [ 20 ].…”
