Abstract
Objective:To explore the MRI manifestations and its diagnostic value for infant brachial plexus injury. Materials and Methods:MRI manifestations and EMG of 15 infants clinical-related materials confirmed to have brachial plexus injury from November 2011 to November 2014 were retrospectively analyzed. Kappa was used to analyze the difference. Results:Seven of fifteen infants had unilateral preganglionic or/and postganglionic brachial plexus injury. Preganglionic brachial plexus injury occurred in 28 nerves and postganglionic injury occurred in 51 nerves, and 12 cases had combined injury. The manifestations of preganglionic brachial plexus injury in MRI included nerve root disappearance or enlargement, nerve root sleeve form abnormality, and meningeal cyst. Postganglionic injury MRI findings showed nerve trunk enlargement, continuity interrupt line with CSF leak, adjacent structure disorder and edema and nerve trunk sheath enlarge. There was no significant difference between MRN and EMG on extent confirm(κ=0.718, P<0.05). Conclusion:MRI is good at revealing brachial plexus injury in early time, and could be rational to the first and review examination.关键词
