Case of steroid refractory dengue myositis responsive to intravenous immunoglobulins.

Dengue is an arbovirus infection that usually presents with the symptoms of high-grade fever, myalgia and rash. Dengue is spread by the mosquito and frequent outbreaks are being reported in regions like Pakistan, India and Sri Lanka. Although muscle ache is quite common with dengue fever, overt myositis is of very rare occurrence. Here, we report a case of a young girl who presented to us with serologically confirmed dengue infection, and having bilateral upper and lower limb weakness. Her raised creatine kinase, along with her electromyography pattern was suggestive of myositis. Her condition was steroid-resistant and responded only to intravenous immunoglobulin. She was discharged in a stable condition.
