Abstract

We describe two unusual cases of benign acute childhood myositis (BACM). A 24-month-old toddler presented with gait disturbance without the elevation of creatine kinase in the hyperacute stage of the disease, which initially led to an erroneous diagnosis. However, the following sample showed an elevation of creatine kinase, and the diagnosis of BACM was made. The other case was a 9-year-old girl who had three successive recurring gait disturbances with a delayed recovery from the third occurrence. Each episode occurred within a short period and was consistent with symptoms of BACM. These two cases may broaden the clinical spectrum of BACM. KeyWords:Benign acute childhood myositis
