Benign acute childhood myositis (BACM) is a rare transient condition that occurs in children during the early convalescent phase of a viral upper respiratory infection. BACM is self-limiting and characterized by sudden-onset bilateral calf pain that leads to difficulty in walking. We report a case of a 5-year-old boy with BACM who presented with acute-onset bilateral calf pain after a resolved episode of viral pharyngitis and subsequently refused to walk. With conservative treatment, the patient recovered completely after approximately 1 week. Although perplexing and challenging for clinicians unfamiliar with BACM, awareness of this rare clinical condition is essential to preventing unnecessary investigations and reassuring the patient and parents of its excellent prognosis.
良性急性儿童肌炎（BACM）是一种罕见的短暂性病症，发生于儿童病毒性上呼吸道感染的早期恢复期。BACM具有自限性，其特征为突发双侧小腿疼痛，导致行走困难。我们报告一例5岁患BACM的男孩，在病毒性咽炎症状消退后出现急性双侧小腿疼痛，随后拒绝行走。经保守治疗，患者约1周后完全康复。尽管对于不熟悉BACM的临床医生来说，这一病症令人困惑且具有挑战性，但了解这种罕见的临床病症对于避免不必要的检查以及让患者和家长放心其预后良好至关重要。
