Magnetic resonance imaging of acute central cord syndrome: correlation with prognosis.
OBJECTIVE
To report the magnetic resonance imaging (MR) findings of acute cervical central cord syndrome and to determine their correlation with the prognosis.


METHODS
MRI findings of 35 patients with acute central cord syndrome were studied and compared with the recovery rate of ASIA score at presentation and in follow-up.


RESULTS
MRI data demonstrated spinal cord compression for 32 patients, spinal cord swelling for 16 patients, and abnormal signal intensity within the spinal cord for 19 patients, including 14 with edema and 3 with hematoma. No significant difference of the recovery rate was noted between the patients treated nonoperatively and operatively (P > 0.05). There was a significant inverse correlation between the recovery rate and the degree of spinal cord compression as shown in MRI scans (P < 0.01). The presence of hematoma in MRI scans was associated with poor prognosis, as demonstrated by a significant difference of the recovery rate (P < 0.01) among the patients with normal intensity, edema and hematoma within the spinal cord.


CONCLUSIONS
MRI scans provide an efficient assistance for decision-making and accurate prognostic information regarding neurological function, and therefore should routinely be performed within the early phase of acute central cord syndrome.
