A case report of a spontaneous sternocleidomastoid hematoma: a challenging diagnosis in infantile neck swellings.

Background: Pediatric neck masses are a common complaint in children. The most common etiologies include congenital lesions, lymphadenopathy, vascular malformations, inflammatory, and malignant lesions. Spontaneous sternocleidomastoid hematoma is exceptional in infant. Case presentation: We describe a case of spontaneous cervical hematoma diagnosed in a 4-month-old child. Past history did not reveal a neck trauma, a history of difficult labor, a bleeding disorder or a pertinent family history. The diagnosis was suspected based on the imaging features and confirmed after surgical removal. Conclusions: Sternocleidomastoid swelling is commonly encountered in infancy. Ultrasound still remains the initial modality of choice. The management modalities are controversial. [ABSTRACT FROM AUTHOR]
