Pediatric torticollis: Not just muscular injury



Broad Categories in the differential diagnosis of pediatric torticollis





Muscular (SCM/trapezius): Most common; typically resolves within a week.





Atlantoaxial Subluxation: C1/2 instability due to ligamentous or osseous abnormalities.





Infectious:



Viral URTI/Pharyngitis → Referred pain, muscle spasm

Retropharyngeal Abscess (typically ages 2–4): Limited neck extension, fever, dysphagia, drooling, stridor

Osteomyelitis/Discitis: Cervical spine tenderness

Lemierre Syndrome: IJ thrombophlebitis post-oropharyngeal infection → SCM or jugular tenderness/swelling







CNS Lesion (typically painless):



Up to 20% of posterior fossa tumors present with torticollis

* 50% of pediatric malignant brain tumors are located in the posterior fossa

Clinical red flags: headache, vomiting, gait changes, ataxia, focal neuro deficits







Atlantoaxial Subluxation

Risk Factors for Atlantoaxial Subluxation



Ligamentous injury (more common than fracture in children)

Congenital hypermobility: Trisomy 21/Down syndrome, Marfan's Syndrome, Juvenile Idiopathic Arthritis

Grisel Syndrome: Post head/neck surgery with local inflammation → ligament laxity



Physical exam pearl to distinguish atlatoaxial subluxation from muscular torticollis



Muscular torticollis: Head tilts toward spastic SCM

Subluxation: Tilts away from affected side



Imaging for suspected atlantoaxial subluxation





XR: Odontoid and lateral views; assess Atlantodental Interval (≤5 mm if <8 years) - use as screening in low pretest probability patients; be aware than sensitivity is poor

CT: Gold standard when high suspicion or red flags present





Bottom Line



Most cases of torticollis self-limiting, due to SCM muscle spasm

Torticollis >1 week or with neurological findings → Image to rule out subluxation, infection, or CNS lesion
