Imaging manifestations of acute torticollis with rare causes in children

Objective To explore rare causes and imaging manifestations of acute torticollis in children. Methods Data of X-ray, CT and MRI on neck and heads of acute torticollis with rare causes in 30 children were retrospectively analyzed. Results After imaging examinations, cervical vertebra fraction was detected in 3 children, intervertebral disc calcification was found in 9, retropharyngeal abscess was in 5 and infratentorial mass was in 7 cases, whereas epidural hematoma in cervical vertebralis, Kawasaki disease, lymphadenitis, Langerhans cell histiocytosis, osteoblasoma and foreign body in esophagus were diagnosed, retrospectively (each n=1). Conclusion Acute torticollis is not a special characteristic for certain disease. Appropriate imaging method should be used to look for causes of acute torticollis in children.
