Benign Acute Myositis in Children: A Case Series

Raja Arrab et al. Cureus. .

Abstract

Benign acute myositis is a rare and transient condition that usually occurs after a viral upper respiratory infection. Several viruses have been associated with this process particularly influenza B. Viral myositis frequently occurs in school-age children with a male predominance. Patients complain about symmetrical calf muscle pain and uncoordinated gait and functional impairment. The presentation is associated with increased creatine phosphokinase. Benign acute myositis is a self-limiting condition with an excellent prognosis. Myoglobinuria is uncommon but severe. We report a case series of three patients presented with viral myositis. Pediatricians must be aware of this pathology to reach an early diagnosis and avoid unnecessary diagnosis investigations. It is also important to reach out to myoglobinuria, which can lead to renal impairment.

Keywords: benign acute myositis; children; creatine phosphokinase; influenza; myoglobinuria.
