Recognising atypical presentations of benign acute childhood myositis: Insights from a case series and literature review

Benign acute childhood myositis (BACM) is a rare, self-limiting inflammatory condition affecting the skeletal muscle, typically emerging during the early convalescent phase of viral infections. Most patients recover with bed rest, analgesics and adequate hydration. However, atypical presentations can sometimes lead to delayed diagnoses and unnecessary investigations. We report five cases of BACM with unusual presentations at admission: toe walking, crawling, delayed recovery, rhabdomyolysis and recurrence. All patients experienced favourable outcomes and complete recovery upon follow-up. This case series highlights the diverse presentations of BACM, emphasising the importance of increasing awareness for early diagnosis, reducing unnecessary workups and providing proper counselling for parents.
