Pediatr Radiol. 2003 Jul;33(7):492-4. doi: 10.1007/s00247-003-0889-6. Epub 2003 Mar 1.


We describe a 23-month-old boy with pyomyositis of the vastus medialis muscle caused by Salmonella enteritidis. Such focal Salmonella infections are uncommon in soft tissue. It is noteworthy of this case that there were no antecedent signs of gastroenteritis and no underlying medical condition. MRI, in particular the fat-suppressed T2-weighted sequence, is helpful for establishing the diagnosis and differentiating pyomyositis from other pathological conditions.
