A 28 year old woman presented with three weeks of left thigh pain, swelling, and fevers after exercising at the gym. Magnetic resonance imaging (T2 weighted) revealed an encapsulated collection extending from the lesser trochanter to the anterior proximal femur. Vastus lateralis and gluteus minimus muscles were swollen. We diagnosed pyomyositis, drained the collection, and prescribed antibiotics. Pus culture yielded Staphylococcus aureus. Exercise induced pyomyositis should be considered in previously healthy, active young adults with leg swelling and fever. Local trauma, including strenuous exercise, facilitates haematological access of bacteria to damaged muscle.
