Abstract
A case of non-tropical pyomyositis in a healthy, adolescent, 13-year-old boy, affecting the paraspinal muscles is presented. Computerised axial tomography scan (CT scan) of the spine provided valuable information on the nature, extent of the disease and helped to plan successful surgical management. None of the reported cases of such severity of paraspinal pyomyositis had involvement of quadratus lumborum muscle or compression on retroperitoneal organ as in our case.
