Focal myositis is a self limited, benign, inflammatory pseudotumor of skeletal muscle, which spontaneously regresses. A 10-year-old girl presenting with localized swelling of the left sternocleidomastoid muscle was seen with subsequent biopsy proven focal myositis. This is the second report of this distinct disease presenting in the neck and the first in the pediatric age group. Biopsy is the only diagnostic and therapeutic modality necessary.
局灶性肌炎是一种自限性、良性的骨骼肌炎性假瘤，可自发消退。一名10岁女孩因左侧胸锁乳突肌局部肿胀就诊，随后活检证实为局灶性肌炎。这是该罕见疾病在颈部出现的第二例报告，也是儿科年龄组中的首例。活检是唯一必要的诊断和治疗方式。
