Abstract

Influenza B virus infections appear to be more common extra-respiratory tract symptoms, compared to influenza A virus infections. Benign acute childhood myositis (BACM) is a benign disease that is caused mainly by many viruses like influenza A or B virus infection. Usually BACM is fully cured with only supportive treatment without unnecessary investigation or invasive procedure. This report describes an eight-year-old boy with acute bilateral calf pain and walking difficulty who diagnosed with BACM after influenza B virus infection.
