When Leg Pain Is Not Just a Pain in the Leg

This is a case of a 12-year-old boy who complained of unilateral leg pain for 1 month with associated low-grade fevers, weight loss, and joint pain. He was noted on examination to be small for age and had a significant heart murmur. He was subsequently diagnosed as having acute infective endocarditis with septic emboli to the leg causing microabscesses in the calf muscles and leg pain. This case also illustrates the important role of translation in the presence of a language barrier.
