A Case of Multifocal Pyomyositis by Staphylococcus aureus / 감염과화학요법

ABSTRACT

Pyomyositis, the suppurative infection of skeletal muscle, is rarely found in areas of temperate climates unless the patients have immune suppressing conditions such as diabetes, human immunodeficiency viral infection, or chemotherapy. Most reported pyomyositis cases in Korea showed localized involvement in only one or two muscles. Previously, no case of pyomyositis with multifocal metastatic dissemination has been reported in Korea. This case of pyomyositis in 51 year old man involved multiple muscles including the chest wall muscles, abdominal muscles and pelvic muscles. Pus culture results revealed Staphylococcus aureus as the causative organism. Delayed diagnosis and prior treatment of two months before visiting our hospital were considered as the causes for the metastatic dissemination of the organism. After 1 month of treatment with aggressive surgical drainage and intravenous cefazolin the patient fully recovered.
