Tuberculosis pyomyosits of the soleus muscle in a fifteen-year-old boy.

Skeletal muscle infection caused by Mycobacterium tuberculosis is rare and usually caused by invasion from adjacent structures. We describe a 15-year-old male youth with tuberculous right inguinal lymphadenitis and right calf swelling who had tuberculous pyomyositis of the soleus, probably resulting from hematogenous seeding. Tuberculosis should be suspected as the cause of pyomyositis, especially if present elsewhere.
