Insights
Fibromatosis colli, a benign congenital neck mass in infants, can cause torticollis. This case showed spontaneous regression within 3 months, highlighting a non-invasive outcome for this sternocleidomastoid muscle condition.
Area of Science:
- Pediatric Medicine
- Musculoskeletal Disorders
- Congenital Abnormalities
Background:
- Fibromatosis colli is a rare, benign congenital tumor affecting the sternocleidomastoid muscle in infants.
- It can lead to torticollis due to muscle tightening.
- Early diagnosis and monitoring are crucial for management.
Purpose of the Study:
- To report a case of fibromatosis colli in an infant.
- To illustrate the diagnostic process using ultrasound sonography.
- To document the spontaneous regression of the condition.
Main Methods:
- Case report of a 3-week-old infant presenting with a neck mass and reduced head mobility.
- Diagnosis confirmed via ultrasound sonography.
- Clinical observation for spontaneous regression.
Main Results:
- Ultrasound sonography confirmed fibromatosis colli.
- The infant's neck mass and associated torticollis resolved spontaneously.
- Complete regression occurred within 3 months without intervention.
Conclusions:
- Fibromatosis colli can resolve spontaneously in infants.
- Ultrasound is effective for diagnosing this condition.
- Conservative management may be sufficient, avoiding surgical or physical treatment.
Abstract:
Fibromatosis colli is an uncommon benign, congenital fibrous tumor or pseudotumor of the sternocleidomastoid muscle that manifests in infancy. In some of these patients tightening of the muscle results in torticollis. We report the case of a 3-week-old child, who presented with a neck mass localized in the left side with reduced mobility of the head. The diagnosis of fibromatosis colli was raised by ultrasound sonography. The mass regressed spontaneously within 3 months without surgical or physical treatment.
