It was a one month old female infant. He was sent to us on 03/22/2019 at the radiology department of Mopti’s hospital for a cervical ultrasound in the assessment of a cervical swelling observed by his mother a few days after his birth with a slight inclination of his head. Ultrasound exploration revealed a fusiform thickening of the left sternocleidomastoid muscle (SCM) with respect for its fibrillar appearance without other abnormalities. The diagnosis of fibromatosis colli of the left SCM muscle was retained. Fibromatosis colli is relatively rare in our environment. Complementary ultrasound at the clinic allows it diagnosis. The typical ultrasound image is the fusiform thickening of the sternocleidomastoid muscle with preservation of its fibrillar appearance. Ultrasound can also rule out other causes of cervical swelling in children.
